Beamspace MIMO system with different elements distances in ESPAR array antenna

Abstract

In this paper, we evaluate performance of beamspace MIMO(Multiple-Input Multiput Output) system using three-element ESPAR antenna according to distance of ESPAR(Eletronically Steerable Parasitic Array Radiator) antenna array when transmitting two BPSK(Binary Phase Shift Keying) symbols. Through the simulation, we confirm that three-element ESPAR antenna can transmit two BPSK symbols, and performance degradation can reduce by changing a reactance of parasitic element.
