Abstract
There are provided an antenna, an antenna tuner configured to adjust frequency characteristics of the antenna, and a control circuit configured to change frequency characteristics of the antenna tuner in a boundary time set for a unit of time of communication. For example, after matching indicators based on VSWRs and received signal strength indicators based on RSSIs have been acquired in a plurality of times of communication space time, the antenna tuner is put into an optimum mode. This suppresses the decrease in communication throughput caused by the adjustment of the antenna tuner and suppresses the interruption of communication at the time of adjustment of the antenna tuner.
