US Patent Issued to NEOLOGY on Oct. 6 for "Controlled reduction of read range of UHF RFID tag" (California Inventor)

ALEXANDRIA, Va., Oct. 6 -- United States Patent no. 12,755,125, issued on Oct. 6, was assigned to NEOLOGY INC. (Carlsbad, Calif.).

"Controlled reduction of read range of UHF RFID tag" was invented by Tareef Al-Mahdawi (Escondido, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "An RFID tag antenna system comprises a tag antenna with complex impedance and an integrated circuit (IC) with input impedance. A controlled mismatch between the tag antenna and IC impedances reduces the realized gain of the tag antenna to a desired level. The system calculates a reflection coefficient to reduce antenna gain by a predetermined amount. A program converts the reflection coefficient to realized gain and calculates th...
