Abstract
A Radio Frequency (RF) microstrip antenna employs a planar or curved radiator element that is mounted or supported in spaced relation to a planar or curved ground plane element. A RF feed is attached near one edge of the radiator element for receiving and/or transmitting RF signals in a lobe that is substantially perpendicular to the ground plane element. The radiator element and the ground plane element are maintained in a converging or tilted physical relationship. When a coaxial cable is employed as the antenna feed, the cable's outer insulation is secured to the ground plane element, the cable's center conductor extends away from the ground plane element to provide a signal feed to the radiator element and to provide physical support for one edge of the radiator element, and two insulator posts extend away from the ground plane element to provide support for the opposite edge of the radiator element.
