Mobile Device Antennas Patents: Top Companies & Trends 2026
- Filings have been flat or declining since the 2019 peak of 987, with the most recent full year running well below that mark — a maturing claim space, not a growing one.
- The ranked leaders hold only 21.2% of all 292,267 records between the top 10, so no single filer controls the field; a long tail of entrants files the rest.
- Momentum has cooled sharply at the top, with several major historical filers showing zero filings and year-on-year drops of 80-100% in the latest tracked year.
What this landscape covers
This dataset tracks patent activity in mobile device antenna design and RF integration — the engineering problems of fitting antennas into handsets and wearables while managing hand and head loading detuning, SAR compliance, multi-band and MIMO operation, ground-plane clearance, and antenna co-design with other RF and mechanical components. The scope spans 292,267 published records filed between 2015 and mid-2026, giving a broad view of how claim activity has moved through the smartphone maturity cycle and into adjacent form factors.
Because publication lags filing by roughly 18 months, the most recent year in the trend is understated and should be read as a floor, not a ceiling. The picture that emerges is one of a technically mature field: heavy claim density in the core antenna subclass, a wide but shallow set of adjacent transmission and networking classes, and a filing curve that has been declining from its 2019 peak rather than climbing toward one.
Let an AI agent run this analysis on your own technology
Pick a task. Every answer cites the patents behind it.
Filing trend and technology composition
Two views of the same 292,267 records: how filing volume has moved year over year, and how the classification codes attached to those records distribute across the IPC system.
A declining curve after a 2019 peak
Annual filings rose to a peak of 987 in 2019, sat near 786 at the 2022 midpoint, and have fallen further since — down to 818 as far back as 2017 and continuing to soften through the most recent tracked years. Read the final year or two as understated given publication lag, but the multi-year direction is clearly down, not up.
Concentrated in the core antenna class, thin elsewhere
H01Q (Antennas) alone carries 5.6% of the 292,267 records in scope, several multiples of any other single subclass. H04B (general transmission) follows at 1.3%, with H04L, H04W, G01S, H01P, H04J and H04M each under 0.5%. Because a record can carry multiple IPC codes, these shares add up to more than 100% of the record total — but the gap between H01Q and everything below it shows where claim density actually sits.
Shares are the percentage of the 292,267 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Multi-band resonance antenna and device including the multi-band resonance antenna (US20250385430A1, Intel Corporation, 2025-12-18)
A multi-band resonance slot antenna forms a slot in a conductive plate, excites it with a trace, and places a tuning stub inside the slot area so the slot's physical length can be shorter than half the wavelength of the target resonance frequency. A second configuration replaces the fixed stub with a tuner circuit that taps an electric trace on a PCB at one or more points to ground, controlled by a signal line, giving reconfigurable multi-band behaviour from a single trace structure.Claim scope and enforceability should be confirmed against the full granted claim set before relying on this summary.

Three reads on the same dataset: where claim density sits, how concentrated ownership is, and what the recent slowdown implies for a team deciding where to file next.
The core antenna class is the crowded one
H01Q carries 5.6% of the 292,267 records in scope — several times the share of any adjacent class. New filings that sit squarely in classical antenna geometry claims are filing into the densest part of the field; adjacent transmission, networking and positioning classes carry a fraction of that density.
No single filer controls the space
The top 10 ranked assignees combine for 21.2% of all 292,267 records, and the top 5 for 15.5%. That leaves close to four-fifths of the field held outside the ranked leaders — a long tail of single- and few-filing entrants rather than a field locked up by a handful of firms.
Historical leaders have gone quiet
Filing volume peaked in 2019 and has trended down through the 2022 midpoint and beyond. Several of the field's historical major filers show zero filings in the latest tracked year with year-on-year drops of 80% to 100%, consistent with a technology that has moved past its most active claiming period.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to mobile device antennas and rf integration, with the prior art for and against each one.
Who is filing, and who has stopped
The ranking covers the 100 companies the data endpoint returns for this search, ordered by patent family count — not a curated top-50 or top-100 list, but the full ranked set available.
A clear leader, but not a dominant one
The leading assignee holds 11,939 records, well ahead of fifth place at 5,403 and tenth place at 2,731. That gap shows a genuine leader in filing volume, but the drop-off by fifth place is steep enough that leadership alone does not translate into field-wide control.
The biggest historical names have nearly stopped filing
Several of the assignees that built the largest historical portfolios in this space show zero or near-zero filings in the latest tracked year, with year-on-year declines of 80% to 100%. That is a strong signal the active claiming period for the core smartphone antenna problem has largely passed for these filers.
Co-filing is rare and mostly intra-group
Only 10 co-assignee pairs appear in this dataset, and the strongest links look like intra-corporate or inventor-linked pairings rather than cross-company joint development. This is a field built mainly on solo corporate filing programmes rather than formal co-development.
| Assignee | Recent year | YoY |

| Huawei Technologies Co., Ltd. | 3 | -80% |
| Qualcomm Incorporated | 0 | -100% |
| Telefonaktiebolaget LM Ericsson (Sweden) | 0 | -100% |

Where to take this analysis
The figures above establish the shape of the field. Turning that into a filing or freedom-to-operate decision means going deeper into specific claim sets and the entities behind them.

Class-level shares show where density sits, but a real FTO read needs claim-by-claim comparison against the granted set in H01Q and the adjacent transmission classes.

The leading assignee in this dataset holds 11,939 records, noticeably ahead of the field. But concentration is limited overall: the top 10 ranked assignees combine for only 21.2% of the 292,267 records in scope, so the majority of filing activity sits with a long tail of companies outside the ranked leaders. A single leadership position in volume does not equate to control of the underlying claim space, since so much of the field is held by smaller filers.
No. Filing volume peaked in 2019 at 987 and has declined since, sitting at 786 by the 2022 midpoint and continuing to soften afterward. Several of the field's largest historical filers show year-on-year declines of 80% to 100% in the most recent tracked year, though the very latest year should be read cautiously because publication typically lags filing by around 18 months.
H01Q, the core antenna classification, carries 5.6% of the 292,267 records in scope, far ahead of any other single class. H04B (general transmission) follows at 1.3%, with digital transmission, wireless networking, radar/positioning, waveguide and multiplex classes each under 0.5%. Since records often carry multiple IPC codes, these are best read as relative density signals rather than an exhaustive breakdown of any one filing.
The clearest gaps sit adjacent to the dense H01Q core rather than within it: reconfigurable slot-tuner circuits, SAR-aware multi-band co-design, ground-plane clearance for foldable devices, MIMO placement for wearables, and waveguide integration in handsets all carry comparatively few records relative to classical antenna geometry claims. These branches are worth a targeted claim search before assuming freedom to file, since low volume in a public search does not guarantee an open path.
Rarely. This dataset identifies only 10 co-assignee pairs, and the strongest of them look like intra-corporate groupings — related entities of the same parent, or inventor-linked filings — rather than genuine cross-company joint development. The field is dominated by solo corporate filing programmes rather than formal antenna co-design partnerships between separate companies.

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.
