Satellite Phased Array Antenna Patents: Who Leads, Where the Gaps Are 2026
- Filing has peaked and declined. activity hit 12 records in 2020, dropped to 3 by 2022, and has kept falling — the architecture space looks largely staked out.
- Calibration patents dominate influence. the five most-cited records in the corpus are calibration and sidelobe methods, some dating to the 1990s, still cited by 2026 filings.
- Software and airborne integration are thin. G06F30 design-optimization claims and B64C/B64D aircraft-integration claims each sit at single-digit record counts inside a 103-record corpus.
What this landscape covers
This landscape tracks 103 patent families filed between 2015 and 2026 that claim satellite phased array antenna work in sidelobe suppression, wide-scan optimization and array calibration, filtered against H01Q3/26, H01Q21 and G06F30. Every record in the corpus touches the H01Q antenna class, with transmission (H04B) and radar/positioning (G01S) as the two largest adjacent technology areas.
Filing activity peaked in 2020 and has declined since, with the most recent years still understated because publication typically lags filing by around 18 months. The most-cited records in the corpus are calibration and sidelobe-suppression methods rather than new antenna architectures, which suggests the field's durable intellectual property sits in how arrays are tuned and verified, not just how they are built.

Filing trends and technology composition
The filing curve and IPC spread below show where claim activity has concentrated and where it has thinned out since 2015.
Filing activity, 2017–2026
Filings rose to a peak of 12 in 2020, fell to 3 by the 2022 midpoint, and have continued to decline; the final year is partial because publication lags filing by roughly 18 months, so 2026's true total will be higher once pending applications publish.
Technology composition by IPC subclass
H01Q (antennas) anchors every record in the corpus at 103, with H04B (transmission) and G01S (radar/positioning) as the two largest adjacent classes at 41 and 29; software-side classes like G06F and aircraft-integration classes like B64C/B64D each carry only 2-4 records.
Shares are the percentage of the 103 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Method and system for calibrating and programming a phased array antenna
A system and method are provided for calibrating and programming a phased array antenna. The system includes a calibration module configured to generate calibrated constellation control codes corresponding to a desired constellation, a look-up table (LUT) for storing the calibrated constellation control codes, and a processing unit configured to program beamforming integrated circuits (BFICs) to produce an RF radiated signal having the desired constellation. A characterization subsystem is configured to capture a characterization subset of the phased array antenna.Filed by C-COM SATELLITE SYSTEMS INC., published 2026-08-06 — illustrates how calibration claims are still being actively filed atop decades of prior art.

Three signals stand out once the raw filing counts are set against IPC composition and citation depth.
Growth has flattened since 2020
The corpus peaked at 12 filings in 2020 and had fallen to 3 by 2022, with the decline continuing toward 2026. Combined with the 18-month publication lag, this points to a maturing claim landscape rather than an emerging one.
Influence concentrates in calibration methods
All five of the most-cited records address calibration or sidelobe suppression rather than raw antenna hardware. That concentration suggests calibration technique, not array construction, is where the durable prior art sits.
Every record sits on the antenna core class
H01Q is present in all 103 families, with H04B and G01S as the largest adjacent classes at 41 and 29. Software-side and airborne-integration classes trail far behind in single digits.
The US and EPO anchor filing venue choice
The United States accounts for the largest share of receiving-office filings at 39, with the EPO at 22 and WIPO/PCT at 13. China, the UK and Canada each register single-digit counts.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to satellite phased array antenna design optimization, with the prior art for and against each one.
Who is filing, and who has stopped
Filing activity is concentrated among a small group of aerospace and satellite-communications assignees, several of whom show no filings in the latest tracked year.
Long-standing filers have gone quiet recently
Boeing, Raytheon, MacDonald Dettwiler and other established assignees in this corpus recorded zero filings in the latest tracked year, including a -100% YoY drop for one major aerospace filer. That does not mean these portfolios are inactive commercially, but it does mean new claim pressure from them has eased.
Collaboration is narrow and recurring
Only 10 co-assignee pairs appear in the corpus, and the strongest pairings repeat between the same organization and named individual inventors, suggesting small, stable engineering teams rather than broad joint-venture filing.
The US remains the primary filing venue
With 39 filings at the US receiving office against 22 at the EPO and 13 via WIPO/PCT, applicants in this space are prioritizing US enforceability first, using PCT filings to keep other jurisdictions open before committing to national phase.

Check claim overlap in EurekaScope a filing in the under-claimed software branch
G06F30 design-optimization claims sit at only 3 records inside this corpus — a joint sidelobe/wide-scan optimization method tied to physical BFIC control is a plausible first claim.
Draft and search in EurekaTrack assignees that have gone quiet
Several established aerospace filers show zero filings in the latest year; monitor whether that reflects a pause or a shift to trade-secret protection before assuming the claim space is open.

The most-cited records in this dataset are calibration-method patents rather than antenna-hardware patents: US5063529A leads with 62 citations, followed by US7362266B2 at 51 and US8872719B2 at 50 for modular phased array tile configuration. High citation counts inside a searched corpus favor older records simply because they have had more time to accumulate citations, so treat these as markers of influence on the field's vocabulary rather than proof that they remain the most commercially relevant claims today. Newer filings, including the 2026 C-COM application, still build directly on this calibration lineage.
Filing activity peaked in 2020 at 12 records and has declined since, with the 2022 midpoint sitting at only 3. That pattern points to a flat-or-declining filing trend rather than sustained growth. Because publication typically lags filing by around 18 months, the most recent years in any such trend will always look thinner than they eventually turn out to be, so the apparent 2025-2026 drop-off should not be read as a hard stop in R&D activity.
Relative to the dense H01Q antenna core (103 of 103 records), several adjacent IPC classes are thin: G06F30 for design-optimization software and G01R for electric/magnetic measurement each carry only 3-4 records, and aircraft-integration classes B64C and B64D carry just 2 each. These gaps sit next to, rather than inside, the most crowded claim territory, which makes them plausible filing targets for teams working on simulation-driven optimization or airborne array integration.
US20260229773A1, filed by C-COM SATELLITE SYSTEMS INC. and published 2026-08-06, claims a calibration architecture that ties a look-up table of constellation control codes to beamforming integrated circuit programming, verified through a characterization subsystem. It blocks calibration workflows built on that specific LUT-to-BFIC sequence, but does not cover real-time control-code computation or alternative characterization designs. Given the depth of prior calibration patents already cited in this space, it should be read as one addition to a crowded calibration stack rather than a new pioneering claim.
The United States receives the largest share of filings in this dataset at 39, followed by the European Patent Office at 22 and WIPO/PCT filings at 13. China, the United Kingdom and Canada follow at single-digit counts. That distribution suggests the US and Europe remain the primary venues where applicants seek enforceable protection, while PCT filings are used to preserve options across multiple jurisdictions before committing to national phase.
