A novel performance diversity modified elliptical patch antenna for C‐band applications

Abstract

A novel modified elliptical patch antenna is designed to provide performance diversity for c‐band wireless applications. Initially antenna A and antenna B are designed to enhance the radiation efficiency and bandwidth, respectively. With the similar patch and substrate size of both antennas by controlling the length of the slots and width of the feed antenna C is designed to yield unique performance in a single element. Antenna C achieves the performance of enhanced radiation efficiency and bandwidth with the reconfigurable mechanism. When antenna C switch to antenna A configuration, it resonates in the frequencies of 3.7, 5.1, and 6.35 GHz have the radiation efficiency of 82.55, 83.3, and 87.09%, respectively and whenever it turns to antenna B configuration it resonates at the bands of 4, 4.8, and, 6.7 GHz have the bandwidth of 260, 300, and 240 MHz, respectively. © 2016 Wiley Periodicals, Inc.
