Terahertz Beamforming Antenna Patents: Leaders & Trends 2026
A data-backed look at terahertz beamforming antenna patents: filing trends through 2026, assignee concentration among 77 records, IPC composition, and where claim space remains open.
Filing growth = 2021 (3 records) → 2024 (7); 2024 is the last year we treat as complete. Top-5 share = the 5 largest assignees ÷ all 77 records in scope (CR5), not the ranked leaders only.
What this patent landscape covers
This landscape draws on 77 published records filed between 2015 and the 2026-08-31 cut-off, searched across IPC classes H01Q, H04B and H04L for terahertz and THz beamforming antenna and phased-array subject matter. The set spans antenna hardware, transmission-layer beam management, and adjacent digital and AI-assisted control claims, giving a working view of where the claim space is dense and where it thins out.
Filing activity was negligible before 2018, accelerated through the early 2020s, and peaked in 2023. Because publication typically lags filing by roughly 18 months, figures for 2025 and 2026 will continue to revise upward and should not be read as a slowdown.

Filing trends and technology composition
The dataset spans 77 published records filed between 2015 and the 2026-08-31 cut-off, drawn from IPC classes H01Q, H04B and H04L. Because publication lags filing by roughly 18 months, the most recent years understate real filing activity.
Filing activity climbed sharply after 2021
Filings moved from 0 in 2017 to a peak of 25 in 2023, with the 2021-to-2024 span alone showing +133% growth (3 to 7 records). Treat 2025 and 2026 figures as still filling in rather than a slowdown.
Publication lags filing by roughly 18 months, so 2025 onwards are still filling in. Growth rates on this page therefore end at 2024; running them to the last bar would understate the field.
Antenna hardware dominates the claim space
H01Q (antennas) appears in 64.9% of the 77 records and H04B (transmission) in 48.1%, confirming that most filings pair array hardware with beam-management or transmission claims. Supporting classes such as H01P (waveguides) and H03H (impedance networks) each sit under 4%, marking them as comparatively open.
Shares are the percentage of the 77 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

US11271619B2 — Method for managing beam considering characteristics of THz antenna
Discloses a terminal and method for beam management in a wireless connection system. The terminal's RF unit and processor receive a beam management region from a base station comprising a reference signal/preamble region, a first transition-time region for transmission beam steering, and a second transition-time region for reception beam steering.Granted to LG Electronics, 2022-03-08 — a frame-timing structure worth checking against any THz terminal beam-management design.

Ranked by citation count within the searched corpus; older records tend to accumulate more citations regardless of current commercial relevance.
Patent titles are shown in the language they were filed in, not translated, so that each record stays verifiable against the original filing — a translated title will not match in Eureka or in any national register.

Three figures from the dataset matter more than the raw counts: where filing concentrates, how fast it moved, and which claim branches remain thin.
A concentrated core, a long tail
The top 10 assignees among the 46 ranked companies hold 62.3% of all 77 records, with the leader alone at 11. That leaves a wide tail of entrants with a handful of filings each — room to move, but only outside the core assignees' claim territory.
Growth is real, not a 2023 blip
Filings rose from 3 in 2021 to 7 in 2024, a 133% increase across the last three fully-published years, with 2023 alone contributing 25 records. Later years will revise upward as publication catches up.
Hardware claims still anchor the field
Antenna-class claims (H01Q) appear in 64.9% of the 77 records and transmission claims (H04B) in 48.1%, confirming the field is still built around physical array design paired with beam-control logic rather than pure software approaches.
Supporting components are thin
Impedance-network claims (H03H) and material-testing claims (G01N) each sit at just 2.6% of records, well below the antenna and transmission core — a gap for filers willing to claim narrower, component-level combinations.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to terahertz beamforming antenna patent landscape, with the prior art for and against each one.

The dataset shows a single strongest co-assignee pair, suggesting joint development across organisational lines is still rare in this field — most filings come from a single assignee acting alone.
Where to take this analysis next
The figures here identify the pattern; deciding how to act on it — where to file, whom to watch, what to license around — takes a closer read of the underlying claims.
Check freedom-to-operate against the concentrated core
With the top 10 assignees holding 62.3% of all 77 records, any new filing in antenna hardware or beam-management timing should be checked against that group's specific claim language before drafting.
Run a claim comparison in Eureka →Test claims in the under-claimed branches
Impedance-network and material-testing classes sit at 2.6% of records each — worth exploring for narrower, component-level claims that avoid the dense antenna-hardware prior art.

The assignee ranking covers 46 companies across the 77 records in scope, with the leader holding 11 records and a clear drop-off toward the tail. The top 5 combined account for 46.8% of all 77 records, and the top 10 account for 62.3%, showing concentration at the top alongside a long tail of single- or few-filing entrants. This pattern means a handful of organisations set the direction of the antenna-hardware and beam-management claims, but the field is not closed to new entrants in the less-crowded branches.
Filing activity grew substantially between 2021 and 2024, rising 133% over that span and peaking at 25 records in 2023. Because patent publication typically lags filing by about 18 months, the lower counts shown for 2025 and 2026 reflect incomplete data rather than an actual decline. Based on the complete years, the trend through 2024 is one of sustained growth rather than plateauing.
Antenna hardware claimed under IPC class H01Q covers 64.9% of the 77 records, making it the dominant claim area, followed by transmission-layer claims under H04B at 48.1%. Digital information transmission (H04L, 16.9%) and wireless network claims (H04W, 13.0%) form a secondary tier. Supporting component classes — waveguides (H01P), material testing (G01N) and impedance networks (H03H) — each sit at or below 3.9% of records, marking them as comparatively under-claimed relative to the core hardware and transmission areas.
The subclasses with the lowest record share relative to the field's overall activity are H03H (impedance networks and filters) and G01N (material analysis and testing), each at 2.6% of the 77 records, with H01P (waveguides) close behind at 3.9%. These areas support the core antenna and transmission hardware but have not attracted the same filing density, which suggests room for claims that tie array performance to specific material characterisation or impedance-matching methods. A narrow claim combining an under-claimed component with a specific THz frequency range is more likely to clear prior art than a broad antenna-geometry claim.
US11271619B2, held by LG Electronics and granted in 2022, defines a terminal beam-management structure with separate transition-time regions for transmission and reception steering — a specific frame-timing element that any similarly structured terminal design should check against. Separately, the two most-cited records in the dataset, US20210288698A1 (190 citations) on reflecting-surface-aided secure communication and US8284102B2 (180 citations) on displaced-feed parallel-plate antenna geometry, represent the claim positions most frequently referenced by later filings. Any freedom-to-operate review in this field should examine all three alongside the filing assignee's broader portfolio for continuations.

Patent data carries inherent limitations: recent filings (typically the most recent 18–24 months) are under-counted due to standard publication lag; counts may be reported at either a patent-family or a patent-record basis and are not always directly comparable; classification, applicant-name, and citation data may contain errors, duplicates, or omissions; and the underlying search query defines and constrains the scope shown.
