Antenna Tuner and Aperture Tuning Patents: Who Holds the Ground
35.0% concentration at the top. The five leading assignees hold 218 of 623 records in scope, so freedom-to-operate work needs to start with a small set of portfolios, not a broad sweep. 2017 is the peak year at 61 records. The comparable complete-year window shows 2021 at 31 falling to 2024 at 26, a -16% move — read the 2025 and 2026 tallies as still filling in rather than as a continued decline.

Common questions on antenna tuner patents
Who holds the most antenna tuner and aperture tuning patents?
One assignee leads the ranked field with 68 records, well ahead of the fifth-place holder at 25. The top five assignees combined account for 218 of the 623 records in scope, or 35.0% of the field, so filing leadership is concentrated rather than evenly spread. Beyond the top ten, which together hold 51.2% of records, the ranking thins into a long tail of smaller and single-filing entrants, which is typical for a mature RF component category with both corporate and individual-inventor activity.
Is antenna tuner patent filing activity growing or slowing?
Filing peaked in 2017 at 61 records and has since moderated; comparing the two most recent complete years, 2021's 31 filings fell to 26 in 2024, a 16% decline over that span. That is a real but moderate pullback, not a collapse. The 2025 and 2026 counts in the raw data look much lower still, but that reflects publication lag of roughly 18 months rather than an actual drop in filing activity — those years will continue to fill in as more applications publish.
What is the difference between an impedance tuner and an aperture tuner in these patents?
Impedance tuners adjust the match between the antenna and the RF front end to compensate for load variation, such as hand or body proximity changing the antenna's electrical characteristics. Aperture tuners instead reconfigure the antenna's effective electrical length or resonant structure directly, often to cover multiple frequency bands from a single physical antenna. A number of records in this corpus, including the representative recent filing on a configurable circuit board, claim both functions from the same switched-component topology rather than treating them as separate designs.
Disclaimer. This analysis is based on Patsnap Eureka data drawn from a limited snapshot of global patent records and is provided for general information and reference only. Patent data carries inherent limitations — recent filings are under-counted because of publication lag, counts may be on a record or family basis, classification and applicant-name data may contain errors or duplicates, and the underlying search query defines the scope shown — so the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
Nothing here is an exhaustive prior-art, novelty, freedom-to-operate or validity search, nor does it constitute legal, financial or professional advice, and it should not be relied upon as such. Verify independently and review with qualified patent and legal professionals before acting on it.
Method: Filing trend and technology composition. Derived from a Patsnap search on Antenna Tuners and Aperture Tuning covering 2015–2026, data cut-off 2026-07-31.
