Dual Polarized Array Antenna With Modular Multi-Balun Board and Associated Methods

摘要

An array antenna includes a modular, multi-layer, multi-balun board structure for use in feeding a dual polarization radiating element. In some embodiments, contacts on a multi-balun board structure may be directly conductively coupled to corresponding feed points of a dual polarization radiating element during antenna assembly. The multi-balun board structure may be inserted into an opening within an aperture board of an array antenna before the contacts are secured to the feed points. Dual balun board structures may be provided for some or all of the radiating elements on the aperture board.

1. An array antenna comprising:
a plurality of dual polarized radiating elements on a first dielectric layer, the plurality of dual polarized radiating elements having a first dual polarized radiating element; and a modular, multi-layer, dual-balun board structure coupled directly to the first dual polarized radiating element, the modular, multi-layer, dual-balun board structure having a first balun to feed a first polarization orientation of the first dual polarized radiating element and a second balun to feed a second, orthogonal polarization orientation of the first dual polarized radiating element, the dual-baler board structure being held substantially perpendicular to the first dielectric layer and extending at least partially through an opening in the first dielectric layer.
