ALEXANDRIA, Va., March 19 -- United States Patent no. 12,255,405, issued on March 18, was assigned to Cypress Semiconductor Corp. (San Jose, Calif.).

"Multipath robust antenna design for phase-based distance measurement" was invented by Zhuohui Zhang (Tustin, Calif.) and Kiran Uln (Pleasanton, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "A system and method reconfiguring an antenna for reducing and/or eliminating the effects of multipath on a phase-based measurement system. The method includes steering an antenna unit into a first direction to cause the antenna unit to generate a first constant tone (CT) signal based on a plurality of multipath signals. The method includes performing a phase measure...
