WIRELESS LOCATION DETECTION AND/OR TRACKING DEVICE AND ASSOCIATED METHODS
First Claim
1. A wireless detection beacon for use with a Radio Frequency (RF) interrogator transmitting at a first frequency and receiving at a second frequency, the wireless detection beacon comprising:
- a substrate;
a power supply carried by said substrate;
an antenna assembly carried by said substrate;
a local oscillator carried by said substrate and configured to be powered by said power supply to provide a local oscillator signal at a third frequency; and
a mixer carried by said substrate and coupled to said antenna assembly and the local oscillator, said mixer configured to generate an outgoing beacon signal to the antenna assembly at the second frequency based upon mixing an incoming signal from the RF interrogator at the first frequency with the local oscillator signal at the third frequency.

Abstract
The wireless detection beacon is for use with a Radio Frequency (RF) interrogator transmitting at a first frequency and receiving at a second frequency. The wireless detection beacon includes a substrate, a power supply carried by the substrate, an antenna assembly carried by the substrate, and a local oscillator (LO) carried by the substrate and configured to be powered by the power supply to provide an LO signal at a third frequency. A mixer is carried by the substrate and coupled to the antenna assembly and the LO. The mixer is configured to generate an outgoing beacon signal to the antenna assembly at the second frequency based upon mixing an incoming signal from the RF interrogator at the first frequency with the LO signal at the third frequency.
