MULTIPLE PARASITIC COUPLING TO AN OUTER ANTENNA PATCH ELEMENT FROM INNER PATH ELEMENTS

摘要

An antenna array is disclosed wherein radiators are parasitically coupled to eac h other forming an efficient feed network. Parasitic coupling of patches is arrang ed so that some patches are fed by a plurality of other patches which are parasitically cou pled thereto. The resulting array is low profile and high gain. By providing patches on different layers with different dimensions, a broadband design for the antenna a rray is achieved.
