<p>Antenna switching equipment (1) switches antennas (3A, 3B) for a reader/writer (2). A power generation unit (11) generates electric power from an RF signal outputted from the reader/writer (2). A switching signal generation unit (12), operating on electric power generated by the power generation unit (11), generates a switching signal for specifying an antenna port to be used from among a plurality of antenna ports (14A, 14B). A high frequency switch unit (13), operating on electric power generated by the power generation unit (11), switches a connection between the reader/writer (2) and one of a plurality of antenna ports (14A, 14B) based on a switching signal generated by the switching signal generation unit (12).</p> |
