<p>An antenna is disclosed for increasing the gain of, or shaping the pattern of, a radiated radio frequency signal. The antenna includes a waveguide (10) for directing the radio frequency signal or for receiving directively the radio signal, a first conductive reflector (22) disposed beneath the waveguide and extending beyond the aperture (12) of the waveguide for reflecting certain of the waves emanating from or entering the aperture of the waveguide, and a second reflector (16) which may be the mounting surface, disposed beneath the first reflector and extending beyond the first reflector for reflecting other of the waves emanating from or entering the aperture of the waveguide.</p> |
