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(shuō)明書(shū)

It should be appreciated that process 1700 is illustrative and that there are variations. For example, although in the illustrative embodiment of FIG. 17, the location of the target device is estimated from two distance measurements (a measurement of distance between the master interrogator and the target device and a measurement of distance between a receive-only interrogator and the target device), in other embodiments, more than two distance measurements may be used to determine the location of the target device. For example, in some embodiments, each of multiple receive-only interrogators (e.g., each of two, three, or four receive-only interrogators) may be used to obtain a respective distance measurement to the target device such that, together with the distance measurement obtained by the master interrogator, three or more distance measurements may be used to determine the location of the target device.

Having thus described several aspects some embodiments, it is to be appreciated that various alterations, modifications, and improvements will readily occur to those skilled in the art. Such alterations, modifications, and improvements are intended to be within the spirit and scope of the present disclosure. Accordingly, the foregoing description and drawings are by way of example only.

The above-described embodiments of the present disclosure can be implemented in any of numerous ways. For example, the embodiments may be implemented using hardware, software or a combination thereof. When implemented in software, the software code can be executed on any suitable processor or collection of processors, whether provided in a single computer or distributed among multiple computers.
