Abstract

A compact multiple-input multiple-output whose ports are exited with CPW feeding configuration is proposed here.This configuration having very good isolation properties between the antennas incorporated (>-20 dB).The four antennas are placed symmetrical around the axis gives a band with in UWB range specified by FCC (3.1GHZ-10.6GHZ).Each UWB antenna element in this configuration having a hybrid fractal which composed of Sierpinski Carpet and Koch geometry.Hybrid fractal geometry along with CPW feed gives wider band width. In order to Improve the mutual coupling between the antennas two stubs are attached in the ground plane for each antenna element. The Hybrid MIMO antenna works on frequency band 2.4GHz-11GHz with a mutual coupling lower than -20dB and Envelop Correlation Coefficient lower than 0.01.
