Satellite Phased Array Antennas Patents: Leaders & Trends 2026
- Concentration is modest. the top 5 assignees hold 22.4% of all 1,206 records and the top 10 hold 35.9% — no single company controls the field.
- Filings peaked in 2023 at 95, and the complete-year comparison shows a 48% drop from 75 filings in 2021 to 39 in 2024.
- Antenna hardware claims dominate, with H01Q covering 74.9% of records versus 5.7% for AI-based beamforming (G06N) — a gap worth watching.
Filing growth compares 2021 (75 records) with 2024 (39) — 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 1,206 records in scope (CR5), not by the ranked leaders only.
What this landscape covers
Satellite phased array antenna patents span active antenna arrays, multibeam antenna configurations and direct radiating array designs, filtered against practical engineering constraints: beam steering resolution, grating lobe suppression, element thermal dissipation, on-orbit calibration and scan loss. That combination captures hardware and control claims together, rather than antenna geometry in isolation.
The 1,206 records in scope run from 2015 through the 2026-07-31 cut-off. Because publication lags filing by roughly 18 months, the final two years of the trend understate real filing activity and should be read as provisional rather than declining.

Filing trend and technology composition
Two views of the same 1,206-record dataset: how filing volume moved year over year, and which IPC subclasses carry the claim density.
Filing trend, 2017–2026
Filings rose from 64 in 2017 to a peak of 95 in 2023. The only complete-year comparison available, 2021 to 2024, shows a 48% decline from 75 to 39 filings — a real contraction, not an artifact of publication lag, though the 2025-2026 figures will still revise upward as later filings publish.
IPC subclass composition
H01Q (antennas) appears in 74.9% of records, confirming this is fundamentally an antenna-hardware field. H04B (transmission) and H04W (wireless networks) trail at 34.0% and 14.4%. Smaller classes — H01P waveguides, H04L digital transmission, G06N AI-based computation, F21S lighting and G10L audio — each sit at 5-7% of records, marking narrower but still active sub-areas. Because records can carry multiple classes, these shares sum to well over 100% and should not be added together.
Shares are the percentage of the 1,206 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

US11658423B2 — Multibeam antenna comprising direct radiating array and reflector
A multibeam antenna comprises a direct radiating array (DRA) comprising a plurality of radiating elements, a reflector facing the DRA so as to reflect a field generated by the DRA, and a DRA controller configured to control the plurality of radiating elements of the DRA according to a plurality of coefficients, such that the field generated at the DRA produces a plurality of beams when reflected by the reflector. The DRA controller determines the coefficients using a bifocal antenna model that references an equivalent bifocal antenna's subreflector and feed horn arrangement.Filed by Airbus Defence and Space Limited, published 2023-05-23.

Three patterns emerge from filing trends, assignee concentration and citation behaviour that matter for anyone deciding where to file or partner next.
No single company controls the field
The leader holds 73 records against a fifth-place figure of 36 and a tenth-place figure of 29 — a gradual taper rather than a cliff. Combined with a long tail across the ranked 100 assignees, this points to a field still open to new entrants rather than one locked up by a handful of incumbents.
Complete-year filings are contracting
The only comparison spanning fully-published years shows a real decline from 75 filings in 2021 to 39 in 2024. Filing peaked at 95 in 2023, meaning the drop is recent and worth confirming as later 2025-2026 publications land, since publication lag of roughly 18 months still leaves those years incomplete.
Hardware claims crowd the field; AI-linked beamforming does not
Three-quarters of records touch antenna hardware claims under H01Q, while only 5.7% intersect G06N (AI-based computing). That asymmetry suggests hardware claim space is heavily occupied while algorithmic beam-management approaches remain comparatively lightly claimed.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to satellite phased array antennas, with the prior art for and against each one.
Who is filing, and where the gaps sit
The ranked assignee list covers 100 companies counted in records — not a top-50 or top-100 cutoff, but the full ranking the dataset returns. Filing behaviour ranges from large aerospace and telecom incumbents to single-filing entrants.
The top filer sits well ahead of fifth place
With 73 records against 36 at fifth place, the leading assignee has a meaningful lead, but the gap to the rest of the ranked list narrows quickly rather than falling off a cliff.
US filings dominate, EPO and PCT follow
United States filings (519) lead, with Europe (EPO, 228) and WIPO/PCT (125) as the next largest routes, followed by Canada (56), Germany (52) and Israel (40). This spread indicates the technology is prosecuted across multiple major jurisdictions rather than concentrated in one office.
Co-assignment is limited but concentrated
Only 10 co-assignee pairs appear in the dataset, with the strongest pairing recording 34 shared filings — a sign that most work in this field is filed by a single assignee rather than through joint ventures or shared ownership structures.
| Assignee | Recent year | YoY |
|---|---|---|
| Outdoor Wireless Networks LLC | 2 | -89% |
| TRAN BAO | 0 | -100% |
| American Vehicular Sciences LLC | 0 | — |
| CommScope Technologies LLC | 0 | — |

Where to take this analysis
The dataset points to a field with moderate concentration, contracting complete-year filings, and lightly claimed algorithmic branches. The next step is turning that into a filing or freedom-to-operate decision specific to your technology.

The ranked assignee list covers 100 companies, with the top filer holding 73 records compared with 36 at fifth place and 29 at tenth. Filing is moderately concentrated: the top 5 assignees together hold 22.4% of all 1,206 records in scope, and the top 10 hold 35.9%. That leaves a substantial long tail of assignees with smaller filing counts, so the field is not locked up by a single dominant player.
Filings peaked at 95 in 2023 after rising from 64 in 2017. The only reliable complete-year comparison, 2021 to 2024, shows a 48% decline from 75 to 39 filings. Because publication typically lags filing by about 18 months, the 2025 and 2026 figures in any raw trend chart are still filling in and should not yet be read as confirming or reversing that decline.
H01Q (antennas) is the dominant class, appearing in 74.9% of the 1,206 records in scope, confirming this is primarily an antenna-hardware field. H04B (transmission, general) and H04W (wireless networks) follow at 34.0% and 14.4%. Smaller but active classes include H01P (waveguides and microwave elements), H04L (digital transmission), and G06N (AI-based computing), each around 5-7% of records — worth checking individually since a single record can carry several of these classes.
US11658423B2, assigned to Airbus Defence and Space Limited and published 2023-05-23, claims a multibeam antenna combining a direct radiating array (DRA) with a reflector, where a DRA controller sets element coefficients using a bifocal antenna model. The model derives the coefficients by referencing what an equivalent bifocal antenna's subreflector and feed horn arrangement would produce. This ties the patent specifically to reflector-fed DRA architectures using bifocal-model-based coefficient calculation, rather than to direct radiating arrays or multibeam antennas generally.
Relative to the 74.9% claim density in H01Q antenna hardware, classes like G06N (AI-based computing, 5.7% of records) and G10L (speech/audio, 5.1%) are comparatively lightly claimed, suggesting algorithmic beam-management and calibration approaches have more open claim space than physical antenna structures. Sub-areas such as on-orbit calibration routines and element-level thermal dissipation also show lower filing density than core radiating-element geometry. Confirming true white space requires checking specific claim language against the ranked assignees rather than relying on class-level shares alone.
