Multibeam reflector antenna of the MM waveband

Summary form only given. A multibeam reflector antenna developed for the creation of wireless local networks in the range of 30 GHz and higher is presented in the paper. This antenna may be used as a base station antenna for the creation of a fixed wireless network in an urban environment. The geometric sizes of the manufactured hemispherical module are 2000/spl times/1000 mm, and the reflector curvature radius is 1000 mm. The feeds are implemented by conical horns with an aperture diameter of 16 mm. The reflector sections are made with aluminum sheet rolled over a spherical template. Construction rigidity, to which high requirements are attached in the millimeter-wave range, is provided by a ribbed carcass made of aluminum profiles. Measurements of the feed parameters of the base station antenna and users' antennas of the network have been carried out using an automatic stand for measuring antenna characteristics in the far field at millimeter wavelengths.
