Compact Elliptical Shaped UWB MIMO Antenna with Improved Isolation

This paper presents a compact, Elliptical shaped Multiple-Input-Multiple-output (MIMO) antenna with high isolation used for all Ultra-Wide Band (UWB) applications. The proposed antenna operates in 3.1GHz-13.5GHz with impedance bandwidth of 10.4GHz which includes the unlicensed band 3.1GHz-10.6GHz approved by Federal Communications Commission (FCC) in 2002.This antenna is designed on a FR-4 substrate having dimensions 19mm×32mm×1.6mm.This antenna uses partial ground plane, with two parallel parasitic elements on the ground plane for isolation improvement and achieves peak gain of 4dB at 9 GHz and highest radiation efficiency of 96.70% at 3.5GHz. The antenna characteristics such as the S- parameters, radiation efficiency and peak gain are observed using HFSS. Furthermore the performance of MIMO antenna such as Envelope Correlation Coefficient (ECC) is studied. This antenna possesses mutual coupling less than -25dB over the entire operating band.
