1. An antenna having multiple radiating bands, comprising:

  • a ground plane;

    a feed plate extending generally parallel to and being spaced from said ground plane by a first distance and having a feed connection extending between said feed plate and said ground plane;

    at least one radiating element extending generally parallel to and being spaced from said feed plate by a second distance, andat least one galvanic connector connecting said at least one radiating element at a first location on said at least one radiating element to said ground plane at a first location on said ground plane, said first location on said ground plane being separated from said feed connection by a third distance,said first, second and third distances being selected to achieve desired impedance matching of said feed plate, andsaid feed plate feeding said at least one radiating element at a location corresponding to an impedance substantially greater than 50 Ohm at least one band.
