Compact CPW fed Four Port MIMO Antenna for UWB applications with Wi-Fi/ISM/WLAN Band Notch Characteristics

A compact UWB with WLAN notch-based four-element CPW fed MIMO/diversity antenna is presented in this paper. Multiple elements facilitate the design to transmit and receive signal from all directions enhancing channel capacity diversity performance. The inverted L-shaped stub attached ground enhances impedance bandwidth (10 dB) provides response. Plus cross-shaped decoupling structure accomplished diminish surface current isolation between it more than 20.2 dB port-1 port-4 without affecting radiation pattern. complimentary split ring resonator (CSRR) radiator utilized eliminate Wi-Fi/WLAN band. |S11| of MIMO varies 3.26 GHz 14 which can be portable, Radar, Satellite, wireless applications. simple used correlate isolate elements, therefore acceptable ECC CCL parameters are achieved.
