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

Substrate 522 may be of any suitable type described herein including with reference to substrate 505 of FIG. 5A and, for example, may comprise a printed circuit board (PCB) and/or be manufactured from any suitable printed circuit board materials or other materials capable of supporting propagation of RF signals in a desired range of frequencies. In some embodiments, the substrate 522 may include a frequency selective surface and/or absorbent coating to reduce harmonic coupling among the antennas in device 522 (e.g., reduce harmonic coupling between the interrogator transmit antenna 524 and the interrogator receive antenna 526 and/or reduce harmonic coupling between the target device transmit antenna 528 and the target device receive antenna 530).

In some embodiments, each of antennas 524, 526, 528, and 530 may be fabricated on substrate 522. For example, substrate 522 may comprise one or more conductive layers and each of the antennas 524, 526, 528, and 530 may be fabricated on the substrate 522 at least in part by patterning the conductive layer(s). Each of antennas 524, 526, 528, and 530 may be a planar spiral antenna, a patch antenna, an antenna comprising two linearly polarized antenna disposed perpendicularly to one another, a MEMS antenna, a dipole antenna, or any other type of antenna.
