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

Some embodiments provide for a system comprising a first interrogator device and a second interrogator device. The first interrogator devices comprises: a first antenna; configured to transmit, to a target device, a first microwave radio-frequency (RF) signal having a first center frequency; a second antenna configured to receive, from the target device, a second microwave RF signal having a second center frequency that is a harmonic of the first frequency; and first circuitry configured to obtain, using the first RF signal and the second RF signal, a first mixed RF signal indicative of a first distance between the first interrogator and the target device. The second interrogator device comprises: a third antenna configured to transmit, to the target device, a third microwave RF signal having the first center frequency; a fourth antenna configured to receive, from the target device, a fourth microwave RF signal having the second center frequency; and second circuitry configured to obtain, using the third RF signal and the fourth RF signal, a second mixed RF signal indicative of a second distance between the second interrogator and the target device.
