In this study, a C-band dual-polarized strip-fed aperture coupled stacked patch antenna array for P2P communication is designed. To satisfy the requirements of P2P communication, the reflection coefficient of the designed antenna is -10dB. The gain is 20dB and SLL is better than -15dB in the cardinal and intercardinal planes of the antenna for both polarizations. Additionally, 40dB cross polarization isolation can be achieved. The idea is based on planar array of strip-fed dual-polarized aperture coupled patch antennas with stripline feed networks. By adjusting the amplitude distribution on the feed network, -15dB SLL in both cardinal and intercardinal planes is achieved for both polarizations. In order to block the coupling between feed networks for different polarizations and prevent distortion on amplitude and phase distributions, stripline feed networks are chosen. In this way, cross polarization isolation can be increased as well. Hence, a novel antenna element, dual-polarized strip-fed aperture coupled stacked patch antenna is proposed. The parameters that affect the impedance behaviour of this type of antenna are investigated and examined in detail. Required feed networks to achieve -15dB SLL in cardinal and intercardinal planes are designed. The proposed antenna elements are placed in array structure, connected to feed networks and the resulted antenna array is optimized and analyzed.
