RADIO WAVE LENS ANTENNA SYSTEM AND RECEPTION ADJUSTMENT METHOD OF THE SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a radio wave lens antenna system whereby the position adjustment of a primary radiator simply made even when an azimuth of a geostationary satellite of a communication opposite party is unknown and which is used even when a radio wave reflecting plate is directed in either of horizontal and vertical directions with respect to ground. SOLUTION: The antenna system is provided with: a semispherical Luneberg lens 2; the radio wave reflecting plate 3 located at a bisectional cross section of the sphere of the lens 2; the primary radiator 4 arranged at a focal position of the lens; and a support tool 5 for the primary radiator including a mast 6 bent along the surface of the lens, and the primary radiator 4 is positioned and fixed to the mast so as to provide a prescribed elevating angle in advance. An arm 10 turnable around a lens center is provided to a rear side of the radio wave reflecting plate 3, and the mast 6 is fitted to an outer end of the arm 10 so as to be turned around the arm 10 in the configuration of the lens antenna system 1B.
