MIMO Antenna Systems Patents: Leaders, Trends & White Space 2026
- 787 to 113 in nine years. Filings peaked at 1,078 in 2019 and have declined since, with every major assignee posting double-digit YoY drops into the latest year.
- H01Q dominates, but H04B is close behind. 8,444 records sit in antenna-hardware IPC classes versus 6,721 in transmission-system classes, showing the field splits almost evenly between physical array design and signal-processing claims.
- Co-filing is rare and concentrated. Only 10 co-assignee pairs appear across 12,820 families, and the strongest links pair large corporates with individual named inventors rather than with other companies.
Filing growth compares 2021 (996 records) with 2024 (629) — 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 12,820 records in scope (CR5), not by the ranked leaders only.
What the MIMO antenna patent record actually shows
MIMO antenna systems patents cluster around a narrow technical core: isolation between closely spaced elements, envelope correlation coefficient reduction, beamforming weight computation and spatial multiplexing gain. The search set spans 12,820 patent families filed between 2015 and mid-2026, concentrated in H01Q (antennas) and H04B (transmission) classification codes with meaningful overlap into wireless-network and radar classes. Filing offices skew heavily toward the United States, followed by Europe and China, with WIPO PCT filings indicating a meaningful share of applicants pursuing multi-jurisdiction protection from the outset.
The most-cited records in this corpus date back to the early smart-antenna and adaptive-array era, which is expected: citation counts accumulate over time and favour foundational filings over recent ones. Treat the citation leaders as markers of doctrinal influence on later claim drafting, not as evidence of which techniques are commercially active today.
Filing trend and technology composition
Annual filing volume and IPC distribution for the MIMO antenna corpus, drawn directly from the 12,820-family dataset described above.
A field past its filing peak
Filings rose from 787 in 2017 to a peak of 1,078 in 2019, held near that level through the 2022 midpoint of 905, then declined toward 113 in 2026. Because publication typically lags filing by around 18 months, the final one or two years understate true activity, but the multi-year downward slope from 2019 predates that lag effect and reflects a genuine cooling in new filing.
Antenna hardware and transmission claims split the field
H01Q (antennas) accounts for the largest single share at 8,444 records, with H04B (transmission, general) close behind at 6,721. Secondary classes — H04W wireless networks, H04L digital transmission, G01S radar/positioning, H04J multiplex communication, H01P waveguides and H04M telephony — show the technology's reach into adjacent systems, but each represents a fraction of the core hardware and signal-processing volume.
Shares are the percentage of the 12,820 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Three patterns stand out once filing counts, IPC distribution and citation data are read together.
The peak has passed, not arrived
Filing volume peaked in 2019 at 1,078 and has trended down since, with the 2022 midpoint at 905 still well above the 2026 partial-year count of 113. Even allowing for an 18-month publication lag, the multi-year decline from 2019 through 2022 is a genuine signal that the core claim space around isolation, correlation and beamforming is filling up rather than expanding.
Hardware and signal processing are near-parity
The near-even split between antenna-structure claims (H01Q) and transmission-system claims (H04B) means neither pure mechanical array design nor pure signal-processing method claims can be treated as the safer route — both are heavily populated, and combination claims spanning both classes are common enough to expect prior art on either side.
Co-filing is the exception, not the rule
Only ten co-assignee pairings appear in the entire dataset, and the strongest ones link a corporate assignee to a named individual inventor rather than to another company, suggesting most MIMO antenna IP is developed and held in-house rather than through joint filing arrangements.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to mimo antenna systems, with the prior art for and against each one.

With only 10 pairs identified across 12,820 families, joint-assignee filing is not a meaningful signal of industry partnership in this dataset — most activity is single-assignee.
Who is filing, and who is pulling back
Recent-year momentum figures show sharp year-over-year declines across every major assignee tracked, not a single one bucking the downward trend.
Qualcomm still files the most, but far less than before
Qualcomm recorded 4 filings in the latest year, a 71% drop year-over-year, remaining the most active of the tracked assignees even as its own output contracts sharply.
Intel shows zero filings in the latest year
Intel's recent-year count fell to zero, a complete pullback from prior-year activity, consistent with the broader contraction seen across nearly every assignee in this corpus rather than an isolated event.
Corporate-academic and corporate-inventor pairs lead joint filing
The strongest co-assignee link in the dataset pairs a large electronics manufacturer with a university technology-transfer office, ahead of pairings between a telecom equipment maker and a named individual inventor — both patterns point to narrow, project-specific collaboration rather than broad industry alliances.

| Samsung Electronics Co., Ltd. | 1 | -86% |
| Viasat, Inc. | 1 | -92% |

Where to take this analysis
The trend and assignee data point to a field with occupied core claim space and a shrinking but still-active edge. The next steps depend on whether the goal is freedom-to-operate, acquisition targeting or new filing.
Map claims against the isolation and beamforming core
Before drafting new claims in envelope correlation reduction or beamforming weight computation, check them against the dense H01Q and H04B clusters identified here — this is where prior art density is highest.

Large wireless-infrastructure and chipset makers dominate the assignee ranking in this corpus, with Qualcomm and Huawei among the most active historically. However, recent-year momentum data shows even the leading assignees filing far fewer applications than in prior years — Qualcomm's latest-year count is down 71% year-over-year and Huawei's is down 91%, so raw historical totals overstate current activity. Anyone assessing competitive position should weight recent-year counts more heavily than cumulative totals.
No. Filings rose from 787 in 2017 to a peak of 1,078 in 2019, held near that level through 2022, and have since declined toward 113 in the most recent partial year. Publication lag of roughly 18 months means the final year or two is always undercounted, but the decline is visible well before the most recent years and reflects a genuine slowdown rather than a data artifact.
The corpus is built around isolation, correlation coefficient reduction, beamforming and spatial multiplexing claims within antenna array and MIMO systems. By IPC classification, H01Q (antenna hardware) accounts for the largest share at 8,444 records, closely followed by H04B (transmission systems) at 6,721, with smaller but meaningful volume in wireless networks, digital transmission, radar and waveguide classes. This means both physical array design and signal-processing method claims are heavily populated, not just one or the other.
Filing density is comparatively thin in shared-aperture multi-band panel designs, waveguide-integrated MIMO feed networks, and dual-use radar-communication array claims, based on the IPC and citation distribution in this dataset. These branches sit adjacent to the dense isolation and beamforming core rather than replacing it, so a new claim there would typically need to specify a structural or frequency-domain feature not already covered by the dominant H01Q and H04B clusters. Confirming true white space requires a claim-level search beyond the aggregate counts shown here.
Rarely. Only 10 co-assignee pairs appear across the full set of 12,820 patent families, and the strongest pairings link a corporate assignee with either a university technology-transfer office or a named individual inventor rather than with another company. This indicates that most MIMO antenna intellectual property in this dataset is developed and held by a single assignee, with joint filing the exception rather than a common industry practice.
