A UWB Label Pulse Energy Recovery Circuit

Abstract

For pulse-excited UWB antennas, because the antenna can only radiate part of the frequency energy, but the pulse signal bandwidth is very wide, a circuit for recovering energy of UWB antenna in time domain is designed in this paper. This energy recovery circuit can collect the energy wasted by the original antenna through heating, which is not radiated out, to recharge the battery, so as to achieve energy recycling and improve battery standby time.
