Phased array antenna with lattice transformation

摘要

Structure and method for an aperture plate (104) for use in a phased array antenna (100) is disclosed. The aperture plate (104) includes a plurality of waveguide transitions (106), each with a radiating end, a coupling end (111) and a body portion extending from the radiating end to the coupling end (111). The waveguide transitions (106) are spaced apart from each other wherein at least a pair of waveguide transitions are spaced apart closer to each other at the radiating end than at the coupling end (111). The method of manufacturing an aperture plate (104) for a phased array antenna (100) is also disclosed.
