ABSTRACT:
A representative embodiment of the invention provides an antenna having an electrically conducting ground plane and an array of electrically conducting strips located at an offset distance from the ground plane. Electrically conducting pathways, each attached to the middle portion of the corresponding strip, connect the strips to the ground plane. Electrically conducting lips, each attached to an edge of the corresponding conducting strip, extend about halfway toward the ground plane. The size of the array is smaller than the wavelength of the fundamental radiation mode supported by the antenna. Advantageously, the antenna has a bandwidth about three times larger than that of a comparably sized prior-art patch antenna.
