Abstract:
A reception apparatus comprising:a plurality of antenna sets forming mutually different radiation patterns, each antenna set comprising a predetermined number of directional antennas selected from L directional antennas; a detector that detects a quality of a received signal; a selector that selects, in association with the quality of the received signal, an antenna set from said plurality of antenna sets for use in reception; and a combiner that combines signals received by said predetermined number of directional antennas of the antenna set selected by said selector, wherein the L directional antennas are divided into M antenna groups that each comprises N directional antennas with mutually different radiation patterns; wherein said M antenna groups are disposed on a virtual plane such that each antenna group is disposed on a vertex of a polygon having M vertexes; and wherein said predetermined number of directional antennas constituting the antenna set are selected such that one antenna is selected from each of said M antenna groups.
