摘要

In this research, compact tapered feed 2 × 2/4 ×4 MIMO antenna arepresented and investigated. The proposed MIMO antenna consists of asquare patch and modified rectangular ground, which is chamfered atedges and etched with two semicircular slots. Likewise, obstructioncaused by WiMAX and WLAN interfering bands is also taken care of byintroducing notched filters. WiMAX is removed by embedding an rotatedT-type stub and a C-type slot eliminates the WLAN band. The proposedantenna configuration covers the usable bandwidth of 3.07 to 11.25 GHzfor 2 × 2 MIMO and 2.97 to 11.28 GHz for 4 × 4 MIMO. Also, both theMIMO antennas provide isolation <–20 dB. Proposed MIMO antennas arefabricated and characterized in near, far-field, and diversity performancewhere envelope correlation coefficient, directive gain (DG), total activereflection coefficient (TARC), and channel capacity loss are simulated andmeasured. 4 × 4 MIMO antenna configuration provides stable gain with amaximum radiation efficiency of 91% and monopole radiation patterns.
