Abstract :
A reader antenna for active RFID technology at 433.92 MHz, used for cargo container security, is proposed. The proposed antenna consists of two layer radiating elements excited by a single probe simultaneously. An omnidirectional radiation pattern with Phi-component of electric field is obtained by an electrical loop with uniform and in-phase current as the radiating source. Measured peak gain is 2.9 dBi, and the average gain is 0.92 dBi in x-y plane
