Diversity reception of 920MHz RFID reader antenna in smart-shelf system

A two-dimensional communication sheet is used as a receiving antenna of a smart-shelf system. Radio frequency identification (RFID) is the protocol used in this system to read the tag that includes information of the goods on the smart-shelf system. In this report, the diversity reception where the termination condition is switched between open and short circuits is proposed to improve the diversity gain in the low sensitivity area. The simulation and experimental results are shown.
