Abstract :
This paper presents a new wideband RFID reader antenna for UHF application. By applying log periodic antenna theory, the proposed antenna is achieved by employing three loop wire elements and fed by a pair of crisscross feed line. The proposed antenna exhibits wide bandwidth of 25.2 % operating frequency at UHF band from 811 MHz to 1046 MHz. The return loss and radiation pattern of the proposed antenna are presented.
