Abstract
A device may include a receive antenna input to couple a receive antenna to a receive chain of the device. The device may include a test signal generator to generate a test signal. The device may include a signal coupler between the receive antenna input and the receive chain. The signal coupler may include a first port to inject the first test signal into the receive antenna via the receive antenna input. The device may include a control circuit to monitor an impedance matching of the receive antenna based on one or more characteristics of a reflected signal resulting from the first test signal being injected into the receive antenna. The one or more characteristics of the reflected signal may be dependent on the impedance matching of the receive antenna.
