This project present design of array antenna from type of inset-fed microstrip patch antenna. The antennas are capable to generate dual-polarization radiation pattern oriented at desired location. The designs were simulated using Microwave Studio CST 2009 and were fabricated on FR4 substrate with a dielectric constant ??r = 4.7, tan ?? = 0.019 and thickness = 1.6mm. The simulation and measurement results have been compared. The design of 2x2 array antenna yield a bandwidth of 5% and the gain is. For the measurement setup of radiation pattern, the reference of transmitter is using monopole antenna. In this, situation, the two planes are considered here at an element plane location 45?? and -45??. The element plane designates E-plane for location 45?? and H-plane for location -45??. The gain of the single element antenna almost 4.21 dBi, and the gain of 1x2 arrays is 7.51 dBi. By designing more patch, which is 2x2 and 1x4 array antennas, the enhancement of gain is achieved were 8.734 dBi and 7.944 dBi, respectively. Finally, the result showed that the combination of more patches in array can improve the performance of antenna gain.
