Use of Microstrip Impedance- Measurement Technique in the Design of a BARITT Diplex Doppler Sensor

A computer-aided microstrip impedance-measurement technique, which yields information on microstrip-material properties, is described. The technique is used to investigate the impedence of microstrip-mounted BARITT diodes and of microstrip pad antennas. A Doppler sensor is designed, incorporating the BARITT diode into a microstrip circuit, used in diplex Doppler range-measuring radar.
