Zusammenfassung:This paper present design of array antenna of the type inset-fed microstrip patch antenna oriented at 45deg and -45deg. 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 (epsiv r =4.9, tan sigma =0.019 and thickness =1.6 mm). The simulation and measurement results were compared. The designs of 1times2, 1times4 and 2times2 array antennas yield a bandwidth of 4.5%, return loss les10 dB. The gain of the single element antenna almost 4.21 dBi, and the gain of 1times2 arrays is 5.33 dBi. By designing more patches, the enhancement of gain achieved were 8.734 dBi and 7.944 dBi, respectively.
