NTN Antenna Design Patents: Top Companies & Filing Trends 2026
- Filings peaked in 2020 at 457 and have declined since, with 2026 tracking to just 28 (partial year) — a signal that the claim space around phased array and user terminal antennas is filling in rather than opening up.
- H01Q (antennas) accounts for 2,484 records against H04B's 3,378, meaning most of this corpus sits at the transmission-system level, not the antenna hardware itself — a narrower field than the topic name suggests.
- Momentum has cooled across every major filer, including double-digit percentage declines year-over-year for the most active assignees, with several long-standing names recording zero filings in the latest year.
Filing growth compares 2021 (347 records) with 2024 (348) — a three-year span. 2024 is the most recent year we treat as complete: publication lags filing by roughly 18 months, so 2025 onwards are still filling in and any growth rate that ends there would understate the field. Top-5 share is the combined record count of the five largest assignees divided by all 5,879 records in scope (CR5), not by the ranked leaders only.
What this landscape covers
This dataset tracks patent families at the intersection of non-terrestrial network (NTN) architecture and antenna hardware — phased array antennas, satellite user terminal antennas, and satellite communication antenna design — filed or published between 2015 and mid-2026. The search string pairs NTN/satellite-communication terminology with antenna-specific claim language, which excludes generic satellite-networking patents that do not touch antenna structure or beam control.
Because publication typically lags filing by around 18 months, the most recent one to two years in any trend line understate true filing activity; treat 2025 and 2026 figures as a floor, not a ceiling.
Filing trend and technology composition
Two views of the same 5,879 families: how filing volume has moved year over year, and which IPC subclasses carry the claim density.
A decade of NTN antenna filing activity
Filings rose from 417 in 2017 to a peak of 457 in 2020, held near the midpoint at 287 in 2022, and have since fallen sharply — 2026 stands at 28 on a partial-year count. Read this as a maturing filing cycle rather than a cooling technology: much of the foundational claim territory for phased array and user terminal antenna structures was staked out between 2017 and 2021.
Where the claims sit across IPC subclasses
H04B (general transmission) leads at 3,378 records, ahead of H01Q (antennas proper) at 2,484 — meaning a large share of this corpus claims system- or link-level transmission features rather than antenna structure itself. H04W (wireless networks, 1,013) and G01S (radar and positioning, 392) show meaningful overlap with beam-steering and tracking functions, while B64G (spacecraft, 200) and H01P (waveguides, 153) mark the smaller, more hardware-specific pockets of activity.
Shares are the percentage of the 5,879 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

1-D electronic scanned satellite user terminal antenna
A fixed terrestrial user terminal antenna for use with satellite communication systems, where satellites orbit in a constellation of spaced orbital planes. The antenna comprises a base with a tilt plate carrying a one-dimensional electronically scanned phased array that scans along a single axis, tilting with the plate so the array tracks individual satellites as they move through an orbital plane.Filed by Boeing, published 2003-07-10 — predates the current NTN filing wave by well over a decade and anchors the single-axis scanned phased array approach to user terminal tracking.

Three patterns stand out once filing volume, technology composition and receiving offices are read together.
The wave has crested
Filing activity peaked in 2020 and has fallen every year since, down to 28 in a partial 2026. This is consistent with a technology whose core architectural claims — phased array beam steering, terminal tracking geometry — were largely staked out during the initial NTN build-out between 2017 and 2021.
System claims outnumber antenna claims
H04B (transmission) carries more records than H01Q (antennas), indicating this corpus leans toward link-level and system-level claims that happen to touch antenna function, rather than pure antenna-structure innovation. Filers targeting hardware-specific claim space should expect a thinner, more contestable prior-art layer in H01Q than the headline volume implies.
Filing strategy centres on the US
The United States receives more than double the filings of the next office (EPO), with WIPO (PCT), Australia, Canada and Israel trailing well behind. A filing strategy built only around US and EPO coverage would miss meaningful activity already routed through PCT and secondary offices like Australia and Canada.
Even the active filers are pulling back
The two most active recent filers each show sharp year-over-year declines, and several historically significant names in this space recorded zero filings in the latest year. Momentum has not shifted to a new leader — it has simply slowed across the board, which is a different signal than a competitor emerging to fill the space.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to non-terrestrial network antenna design, with the prior art for and against each one.
Who is filing, and who has stopped
Assignee activity in this corpus is concentrated among a small group of satellite-system integrators and telecom equipment makers, with co-filing patterns pointing to specific engineering teams rather than broad corporate portfolios.
Still filing, but slowing sharply
The most active recent filer in this dataset still leads on raw count for the latest year, but its year-over-year decline of 71% mirrors the broader cooling trend across the corpus rather than bucking it.
Named-inventor pairs anchor key portfolios
The strongest co-assignee pairings in this corpus link a corporate assignee to specific named inventors across six shared families each, suggesting concentrated engineering teams rather than distributed R&D across large organisations.
Long-standing names have gone quiet
Two organisations with substantial historical footprints in satellite and aerospace antenna work recorded zero filings in the most recent year, consistent with the overall decline but notable given their earlier weight in this field.
| Assignee | Recent year | YoY |
|---|---|---|
| SpaceX | 6 | -71% |
| ViaSat | 3 | -81% |
| HUGHES NETWORK SYST | 1 | -50% |
| Qualcomm Incorporated | 1 | -67% |
| The Boeing Company | 0 | — |
| Motorola | 0 | — |
| Hughes Network Systems | 0 | — |
| Mitsubishi Electric Corporation | 0 | -100% |
Where to take this analysis
The trend and composition data point to a field with declining filing volume but uneven claim density across sub-areas — the next steps depend on whether the goal is freedom-to-operate or new filing.
Check freedom-to-operate in the under-claimed pockets
The gate chips above flag sub-areas with thinner claim density than the corpus average. Before filing there, run a targeted prior-art search on those specific claim elements rather than relying on the aggregate H01Q count.
Explore in EurekaTrack the assignees still active despite the decline
A small group of filers continues to file even as overall volume falls. Watching their claim language year over year is a better early-warning signal than the aggregate trend.
Run assignee monitoring in EurekaRe-run this search as new publications land
Because publication lags filing by roughly 18 months, the 2025-2026 figures in this dataset will rise as more records surface. Re-checking the trend in six to twelve months will sharpen the read on whether the decline is real or a reporting artefact.

In this landscape, it is a patent family whose claims combine NTN or satellite-communication system language with antenna-specific structure — phased array antennas, satellite user terminal antennas, or satellite antenna design. Patents that describe general satellite networking without touching antenna hardware or beam control are excluded from this search, which is why the total (5,879 families) is narrower than a broad 'satellite communication' search would return. This distinction matters if you are benchmarking against a different dataset that used looser search terms.
The filing trend shows growth from 417 in 2017 to a peak of 457 in 2020, then a steady decline to 28 in the partial 2026 year. This pattern is typical of a technology area where the core architectural claims — array geometry, beam-steering methods, terminal tracking logic — were staked out early in the NTN build-out cycle, leaving less open ground for follow-on filings. It does not necessarily mean commercial interest has declined; publication lag of roughly 18 months also means the last one to two years understate true activity.
The recent-year momentum data shows a small number of assignees still filing, though every one of them shows a year-over-year decline — the leading filer is down 71% and others are down further. Several organisations with substantial historical portfolios in this space recorded zero filings in the latest year. This suggests the active filer base has narrowed rather than a new leader emerging to take share.
The clearest signal is the gap between H04B (transmission-level claims, 3,378 records) and H01Q (antenna-structure claims, 2,484 records) — a large share of this corpus claims system or link behaviour rather than antenna hardware itself, leaving hardware-specific structures comparatively less contested. Sub-areas like multi-beam tracking handover geometry, waveguide-integrated feed structures, and low-profile flat-panel terminal antennas show thinner claim density relative to the corpus average, though a targeted freedom-to-operate search is still needed before filing there.
The United States dominates as a receiving office with 2,372 records, more than double the EPO's 906. WIPO (PCT) filings sit at 533, with Australia, Canada and Israel each in the low hundreds. A filing strategy that only covers the US and EPO would miss a meaningful share of activity already routed through PCT and secondary offices, particularly relevant for satellite-system integrators operating across multiple regulatory regimes.
