Abstract
A wideband antenna system comprises a stack of m antennas, where m is a positive integer, and m≧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 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 antenna provide a ground plane for the k antenna, where i and k are positive integers, 1≦k≦(i−1), and 2≦i≦m. The total area of the first and second radio frequency elements of the i antenna is greater than the total area of the first and second radio frequency elements of the k antenna.
