Abstract
A Doppler radar sensor includes a radar and a bondwire interconnection. The bondwire interconnection is connected to a signal generator and an antenna of the radar and configured to transmit a radio frequency signal generated by the signal generator to the antenna and transmit a reflected signal received by the antenna to a demodulator of the radar. A metal strip, a first shunt bondwire and a second shunt bondwire of the bondwire interconnection can be used as a matching circuit of the antenna to decrease the transmission loss and increase the detection distance of the radar.
