Abstract
Electronically steerable parasitic array radiator (ESPAR) antenna using analog RF switches for single RF chain is presented. A switch simplifies the design and implementation of reactance loads, does not require complex additional antenna matching circuits. The measured impedance bandwidth of the proposed ESPAR antenna is 650 MHz (2.35-3 GHz). The proposed antenna has a beam pattern is reconfigurable in the 2.45 GHz due to a change in the reactance value, the measured peak antenna gain is 4.5 dBi.
