发明名称 ANTENNA SYSTEM
摘要 PROBLEM TO BE SOLVED: To provide an antenna system capable of making a user unaware that the system is an antenna, by reducing the influence of multipath fading and increasing decorative performance. SOLUTION: The antenna system is provided with one feeding element 10 as a conductor straightly from almost the center of a base, a plurality of parasitic elements 11-16 as conductors, extending from almost the center of the base or its vicinity so as to gradually be away from the feeding elements, variable reactance elements 21-26 mounted on each parasitic element, and an antenna controller 33 for making reception sensitivity in the feeding elements to the maximum by varying each reactance value of each variable reactance element.
