Abstract
A microstrip antenna includes an annular conducting element spaced by a dielectric element from a conducting ground plane and radiating circular polarization in a conical elevation pattern. A central whip antenna may be located on the axis of the annular-shaped element. Another microstrip antenna having an annular conducting element may be dielectrically spaced from the first-mentioned annular conducting element that comprises the ground plane for the second annular-conducting element.
