This work presents a rectangular microstrip patch antenna for dual polarization applications at 8 GHz. Roger's substrate has been used as a dielectric material with loss tangent 0.0027 and relative permittivity as about 3.55. The transmitter and receiver ports of the antenna operates at different instants. Therefore, their insertion loss must meet at below -3 dB. Genetic Algorithm (GA) was used in the selection of various physical parameters of antenna to bring the return loss (SII) under - 10dB. Another requirement of the proposed antenna gain must be above 4 dBi at both ports (transmitter and receiver). Therefore, a multi-objective fitness function was considered to optimize the proposed antenna electrical performance and gain based on the tournament selection in GA. After achieving the matching and gain performances as per the requirement, the radiation patterns were analyzed in E-plane and H-plane.
