摘要

A device comprising: a substrate; a semiconductor die mounted on the substrate; a transmit antenna fabricated on the substrate and configured to transmit radio-frequency (RF) signals at least at a first center frequency; a receive antenna fabricated on the substrate and configured to receive RF signals at least at a second center frequency different than the first center frequency; and circuitry integrated with the semiconductor die and configured to provide RF signals to the transmit antenna and to receive RF signals from the receive antenna.

說明書

After receiving the target device's responsive RF signal, interrogator 1402 may use the responsive RF signal and a version of the transmitted RF signal to generate a first mixed RF signal indicative of a distance between the interrogator 1402 and the target device. Each of receive-only interrogators 1404, 1406, and 1408 may receive, via lines 1412, a fixed-frequency reference signal and generate, using the received fixed-frequency reference signal, a local version of the RF signal transmitted by master interrogator 1402. Next, each of receive-only interrogators 1404, 1406, and 1408 may receive a respective responsive RF signal from the target device and may generate, using the received responsive RF signal and a respective local version of the transmitted RF signal, a respective mixed RF signal indicative of a distance between the receive-only interrogator and the target device.
