Abstract:
1. A wireless communication system, comprising: a transceiver configured to transmit and receive communication signals at a first operating frequency; a passive radio-frequency identification device separate from the transceiver and configured to transmit and receive communication signals at a second operating frequency different from the first operating frequency; an antenna coupled directly to the transceiver, wherein the antenna is configured to receive communication signals at the first operating frequency for processing by the transceiver, and wherein the antenna is further configured to receive communication signals at the second operating frequency for processing by the passive radio-frequency identification device; and a network coupled between the passive radio-frequency identification device and the antenna, wherein the network is configured to match the impedance of the passive radio-frequency identification device to the impedance of the antenna at the second operating frequency so that a communication signal at the second operating frequency is propagated to the passive radio-frequency identification device via the network for processing.
