Abstract
A wideband antenna system comprises a stack of m antennas, where m is a positive integer, and m.gtoreq.2. Each antenna includes: a) an electrically insulating substrate; b) opposed first and second radio frequency elements mounted to the substrate; c) a ground feed electrically connected to the first radio frequency element; d) an excitation feed electrically connected to the second radio frequency element; and e) a ground plane mounted to the substrate of the m.sup.th antenna. The radio frequency elements of each antenna collectively have a unique total area and are mounted to the electrically insulating substrate. The radio frequency elements of the i.sup.th antenna provide a ground plane for the k.sup.th antenna, where i and k are positive integers, 1.ltoreq.k.ltoreq.(i-1), and 2.ltoreq.i.ltoreq.m. The total area of the first and second radio frequency elements of the i.sup.th antenna is greater than the total area of the first and second radio frequency elements of the k.sup.th antenna.
