Abstract:
An antenna system comprising:an antenna main body; a plurality of first antennas disposed within said main body in such a manner as to provide with said antenna system with a plurality of directivities that enable said antenna system to receive radio waves in a first frequency band coming to said main body from a plurality of first different directions around said main body, said antennas being able to be combined to provide said antenna system with a plurality of directivities that enables said antenna system to receive radio waves in said first frequency band coming to said main body from a plurality of second different directions between adjacent ones of said first directions; first selecting means disposed within said main body for selecting one of outputs provided by individual ones of said first antennas and combinations of said first antennas; and control means formed as a unit separate from said main body, said control means providing a selection control signal to said first selecting means; said control means including first and second operating elements, and providing said first selecting means with such selection control signal as to successively scan said directivities of said antenna system in a clockwise direction around the main body each time said first operating element is operated, and with such selection control signal as to successively scan said directivities of said antenna system in the counterclockwise direction around said antenna main body each time said second operating element is operated.
