Abstract:
A direction estimating device includes a plurality of antennas placed on a front surface of a board to have different main lobe directions of directivities, at least one antenna placed on a back surface of the board, a radiowave intensity obtainer that obtains a received signal strength indication (RSSI) of a radiowave received by the plurality of antennas placed on the front surface of the board, and by the at least one antenna placed on the back surface of the board, and an estimator that estimates an arriving direction of the radiowave based on the RSSI of the radiowave obtained by the radiowave intensity obtainer.
