Abstract

This antenna, in particular intended for the transmission of radio or television signals in the decimetric-wave range, comprises: - a vertical, central support tube (100), - a plurality of identical radiating arrays (200), preferably three in number, uniformly distributed around the central tube and each formed from a vertical bifilar line (210, 210') supporting, coupling and supplying in a symmetrical manner, a plurality of horizontal dipoles (220, 220') uniformly distributed along this bifilar line, and - an equipower, equiphase power distribution system, preferably housed entirely inside the central support tube, identically and simultaneously supplying the three radiating arrays from a single coaxial supply line. The antenna lacks a reflector, this significantly reducing its weight and its wind resistance relative to conventional panel antennas generally used in this range. Advantageously, these antennas are superimposed and enclosed in a sealed, essentially cylindrical, self-supporting and superimposable radome. This antenna achieves an omnidirectional pattern at 0.9 dB between 460 and 860 MHz, and can radiate 5 to 7 kW per antenna element. <IMAGE>
