ANTENNA FAULT DETECTOR, ANTENNA FAULT DETECTING METHOD, ANTENNA FAULT DETECTION PROGRAM, AND WIRELESS BASE STATION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an antenna fault detector, an antenna fault detecting method, an antenna fault detection program, and a wireless base station apparatus capable of simply detecting a fault in an antenna with high accuracy.

SOLUTION: Reception level detection sections 12a to 12d detect a reception level of a signal received by a corresponding antenna for each prescribed period. An antenna particularizing section 18 particularizes an antenna whose reception level is minimum and increments the number of times of the antenna reaching the minimum level in a reception level storage section 15. After a lapse of a prescribed time, a fault determination section 16 references the reception level storage section 15 to calculate a ratio of the reception level of each antenna reaching a minimum level. The fault determination section 16 determines antennas whose calculated ratio is a prescribed value or over to be faulty antennas.
