Abstract
An antenna for a land-based, mobile radio communication system, having a reduced size and shape, includes three, flat antenna dielectric panels, each covering one hundred, twenty degrees of azimuth. On each dielectric panel is formed two, interleaved microstrip antenna arrays having narrow vertical beam width. One of the antenna arrays receives signals and the other antenna array transmits signals. The receive array is circularly polarized. The panels are mounted in a triangular configuration about a central mast and a cylindrically shaped radome encloses the dielectric panels.
