An impedance transformer for UHF RFID and WiFi cross‐technology communication‐based tourism crowd counting

Electronics Letters
This letter proposes a novel cross‐shaped structure‐based parallel coupled line transformer and its application to tag antenna for 920‐MHz radio frequency identification (RFID) and 5‐GHz WiFi Cross‐Technology Communication (CTC).

High power, broadband, coaxial to microstrip bi‐directional coupler in the VHF/UHF band

IET Science, Measurement & Technology
Broadband couplers consist usually of multiple coupled lines that are each a quarter wave‐length long. Herein, in contrast to conventional methods, a short length of a microstrip line is coupled to a coaxial line.
