| Summary: | This paper present design of array antenna of the type inset-fed microstrip patch antenna oriented at 45° and -45°. The antennas are capable to generate dual-polarization radiation pattern oriented at desired locations. The designs were simulated Microwave Studio CST. These antennas were fabricated on FR4 board (er=4.9, tan s =0.019 and thickness =1.6mm). The simulation and measurement results were compared. The designs of 1×2, 1×4 and 2×2 array antennas yield a bandwidth of 4.5%, return loss =10dB. The gain of the single element antenna almost 4.21 dBi, and the gain of 1×2 arrays is 5.33 dBi. By designing more patches, the enhancement of gain achieved were 8.734 dBi and 7.944 dBi, respectively.
