ALEXANDRIA, Va., Oct. 8 -- United States Patent no. 12,438,260, issued on Oct. 7, was assigned to Saltenna Inc. (McLean, Va.).
"Surface electromagnetic wave antenna" was invented by Igor Smolyaninov (Columbia, Md.) and Quirino Balzano (Annapolis, Md.).
According to the abstract* released by the U.S. Patent & Trademark Office: "Surface electromagnetic wave (SEW) antennas for maintaining resonance frequency in response to proximity to a conducting surface and related methods are described. In some implementations, an SEW antenna may include a tip with a spherical particle configured to maintain the antenna's resonance frequency when in proximity to a conductive surface. The antenna may feature a resonant helix that supports a strong electri...
