PROBLEM TO BE SOLVED: To make it possible to calibrate output power and phase without requiring an external apparatus.SOLUTION: An antenna apparatus comprises an antenna module 1 including: a transmission unit 121 for outputting transmission power whose output power and phase are controlled; and a switch 124 capable of switching an output destination of the transmission power to a path other than the antenna 11. The antenna apparatus comprises: a comparator 2 for comparing, in each antenna module 1, a transmission power which has been output through a path other than an antenna 11 by a switch 124 with a transmission power from a neighboring antenna module 1; and a computation circuit 3 for controlling, on the basis of a result of the comparison, an amount of gain adjustment and an amount of phase adjustment for the transmission power of a transmission unit 121 in each antenna module 1. |
