摘要： An antenna selection diversity apparatus capable of shortening, when antennas are switched in frame units, a measuring time of antennas and shortening the time of selecting an optimal antenna from among a plurality of antennas on standby. In this apparatus, an antenna selection section (109) selects one of three antennas as an antenna in actual use for a period of a plurality of frames consecutively according to selection priority stored in an antenna information storage section (108) and gives an instruction for selecting one of two antennas on standby as an antenna to be measured once at a period of a plurality of frames to an antenna selection switch (104). When the reception level of the antenna in actual use measured by a reception level measuring section (107) falls below the reception level of the antenna to be measured a predetermined number of times consecutively, the antenna selection section (109) gives an instruction for selecting the antenna to be measured as the antenna in actual use to the antenna selection switch (104).
