FIELD: antenna engineering. ^ SUBSTANCE: hemispherical Luneberg lens is mounted on reflecting plate, antenna components are fixed on holder, and wiring section of locating part is formed for actually vertical installation of reflecting plate on wall surface. Reflecting plate can be better fan-shaped, this being obtained by removing all sections except for those used for reflecting radio waves arriving from directions in predetermined band. Hemispherical Luneberg lens can be installed on reflecting plate in position shifted in direction opposing that in which lens transmits and receives radio waves. In addition, there is supporting bracket enveloping the lens; antenna components are installed on arc-shaped section of supporting bracket along lens spherical surface incorporating angle adjuster designed to set elevation angle at intervals corresponding to distances between satellites on geostationary orbit by means of setting facility. Supporting bracket is mounted with aid of articulated joints in desired angular position so that antenna components are tuned to desired objects. ^ EFFECT: free choice of mounting position, reduced space requirement and mass. ^ 18 cl, 31 dwg |
