Abstract :
Development and optimization of the aperture-coupled stacked microstrip patch antenna is presented, which has dual polarization with great enhancement of bandwidth. Stacked antenna with aperture feeding mechanism results in great isolation between two feeds. Varying several physical parameters of aperture and matching feed line lengths had very large effect on the performance of the antenna. The microstrip antenna has 42% bandwidth from 7.3 to 11.2 GHz with below 25 dB of isolation between two feeds. The gain was average of 7.5 dBi that highest gain was 10 dBi at feed1 for 9 GHz.
