ABSTRACT:
A wide bandwidth coupler has two outer elements around a center element. The outer elements are rectangular at their outside portions and each have a tapered nose portion next to the center element. A matching network electrically connects the two outer elements and the center element. The center element is connected to a first portion of a signal feed structure, while one of the outer elements connects to a second portion of a signal feed structure.
