Abstract
A system to multiplex antennas for radio-frequency communication uses one or more antenna shorting circuits to selectively enable RF communication via one of a plurality of antenna matching networks. The system is cost-efficient compared to alternatives. The RF communication includes read and/or read/write communication with, e.g., radio-frequency identification (RFID) tags.
