Summary:
The center feed in a single-layer slotted waveguide array [1,2] is the one of the key component of dual polarization fixed wireless access system. Two center feed single layer slotted waveguide arrays with orthogonal polarization in exactly the same frequency are used for transmission and reception, respectively. Each array has bore sight beam. This antenna has extremely high XPD (almost 50dB in measurement) and high isolation (over 80dB in measurement) between two arrays orthogonally arranged side-by-side. On the other hands, the blocking area at the center of the antenna causes the high sidelobe level. The reducing blocking area is required. The ridged cross-junction power divider is proposed to solve above problem.
