A CPW fed antenna design for UWB-MIMO communication system for high isolation

A compact planar monopole ultra wide band (UWB) antenna is described with coplanar waveguide (CPW) feed for MIMO applications. The radiator and ground plane of the antenna are etched onto a piece of substrate with an overall size of 28.5mm × 42mm × 1.524mm. Implication from simulation shows that the antenna achieves a broad operating bandwidth of 3.2–10.6 GHz for a −10 dB return loss and Comb shaped DGS has significantly reduced the correlation of MIMO system. The antenna features Omni-directional radiation pattern with high radiation efficiency of 73.3% to 97.2% across ultra wide band bandwidth.
