Abstract
Disclosed herein is a dual-feed dual-polarized antenna element and a method for manufacturing the same. An embodiment dual-polarization antenna element includes four radiating elements and eight feed ports. The four radiating elements are arranged in a co-planar diamond pattern. The neighboring elements of the four radiating elements form four shared-element dipole antenna elements. Each of the four radiating elements is shared between two cross-polarized dipole antenna elements of the four shared-element dipole antenna elements. The eight feed ports are arranged in four cross-polarized dual-feed pairs respectively disposed on the four radiating elements. Each feed port of the four cross-polarized dual-feed pairs is operable to respectively excite one of the four radiating elements for a cross-polarized one of the four shared-element dipole antenna elements.
