Abstract
In this paper a broadband four ports MIMO antenna with pattern diversity is presented To obtain pattern diversity four microstrip feeding lines are printed on one side of the substrate where as the modified ground plane is printed on the other side These microstrip lines generate orthogonal radiation patterns In annular slot four shorts are placed between the microstrip lines to maintain isolation more than 25dB The antenna operates in the range of frequencies from 2 3GHz to 12 6GHz nearly 139 which covers FCC defined wireless applications Besides FCC the proposed antenna covers WLAN and Wi-Max applications A design and optimization of proposed geometry is done in Ansoft s HFSS 13 Simulated and measured reflection coefficients coupling coefficients and radiation patterns are presented
