摘要

This antenna device for living body measurement comprises: a belt (20) which is worn by being wrapped around a measurement site of a living body; and a transmission/reception antenna group (40E) mounted on the belt (20) and including a plurality of antenna elements (TX1, TX2,..., RX1, RX2,...). In a worn state in which the belt (20) is wrapped around an outer surface of the measurement site and worn, one of the antenna elements (TX1, TX2,...) is used as a transmission antenna to emit radio waves to the measurement site, and one of the antenna elements (RX1, RX2, ...) is used as a reception antenna to receive the reflected radio waves. A transmission/reception antenna pair composed of a transmission antenna and a reception antenna is switched among the plurality of antenna elements and selected or weighted on the basis of the reception output.
