The design of a dual polarized antenna array operating at the center frequency of 9.4 GHz is presented in this thesis. A 2X2 dual polarized antenna sub array is designed on a multilayered structure for operation at 9.4GHz. A series-fed linear array is created using 2X2 sub array structures as elements. Two different layered structures are presented for the sub array structure. For the first structure, the patch radiators and the feed network are designed using a substrate (RT Duroid 5870) with permittivity of 2.33 and a thickness of 0.787 mm. For the second structure, the patch radiators are placed on a substrate (RT Duroid 5870) with height 0.787 mm while the feed network is placed on a different material (TSM DS3) having permittivity of 3 and thickness 0.254 mm. The multilayered sub array was fabricated at Prototron Circuits and the measurements were taken at the Radiation Laboratory at UPRM. For the linear array several amplitude distributions including uniform, Taylor 1-P and Taylor ̅ was considered. The design of the sub array and linear array including results of simulation and experimental results are presented and discussed in the thesis.
