Abstract:
A circularly polarized, multiband, and wideband antenna and can communicate with a GPS system. The antenna may include a driving element, first, second and third conductive parasitic elements electrically connected to the driving element, and a ground plane. The parasitic elements are provided with different lengths to provide for wider band operation with multiple resonant frequencies. The radiated wave has a low angle of propagation and travels for at least 1-2 miles.
