EMERGENCY RESCUE EQUIPMENT COMPRISING A HARMONIC REFLECTOR CIRCUIT

An emergency rescue equipmenthaving a harmonic reflector circuit comprising an antenna connected to a non-linear circuit via a matching circuitand a casing that in part enclose the harmonic reflector circuit, wherein the harmonic reflector circuit is configured to receive a signal at a receive frequency (fRX), and configured to transmit said received signal at a transmit frequency (fTX), where the transmit frequency is a multiple of the receive frequency, the harmonic reflector circuit wherein the receive frequency (fRX) is in an interval from a first frequency to a second frequency, where the first frequency is at least 800 MHz; middle second frequency is at least 34 MHz larger than the first frequency;the received signal is transmitted at the transmit frequency (fTX) with an output power (Pout) of at least 70% of the maximum available output power (Pmax).
