Abstract
Disclosed is a system and method of a switchable, oscillating near-field and far-field antenna that may be used in access control systems. A controller is coupled to a transceiver, wherein the transceiver comprises an antenna module that includes both a near-field antenna and a far-field antenna. The near-field antenna is a subset of the far-field antenna, and the controller is adapted to cause the antenna module to oscillate between a near-field configuration and a far-field configuration while, for example, scanning an RFID tag of a wireless asset and receiving one or more return signals from the RFID tag, in order to determine a location of the wireless asset based on the one or more return signals.
