UHF RFID of People

Abstract

Reliable RF identification of people in moderate 2 ? 10 m ranges must be based on electromagnetic wave coupling mechanism. Due to acceptable antenna dimensions, UHF or microwave operational frequencies must be used. At these frequencies, propagation of electromagnetic waves is influenced by several important physical phenomena, namely by interferences, shadowing or waveguide effects. Besides these, in this application, the functionality of TAG antennas can be negatively influenced by the presence of a nearby
