The main objective of this thesis is to discuss the high gain dual-polarization antennas applied on customer premises equipment of WiMAX application. The primary content includes simulation analysis and experiment measurement on the dual polarization array antennas with different number of array elements and different feed network structure. In Chapter 2, we propose the antenna design composed of two different feeding system, which can reduce the space of the orthogonal polarization configuration and place the feed network on both side of the ground to achieve the goal of gaining the lowest loss and the best radiation efficiency; it has the maximum gain above 8.5 dBi and is suitable for the Indoor CPE application. In Chapter 3, we propose a simplest dual-polarization array antenna design adopting the printed circuit board on which, both the antenna array elements and the feed network are printed on the same plane in order to reduce the space of antenna layout and simplify the feed network design. This conception can achieve the high gain dual polarization antenna effectively. In Chapter 4, we carry on the preceding chapter’s antenna design merit, then we subsitute the antenna array and the feed network structure for the air substrate, which can decrease the antenna feed network transmission loss achieving the optimization high gain radiation efficiency. The entire design can meet the maximum gain above 15 dBi and suitable for the Outdoor CPE application.
