220–270 GHz Waveguide to Microstrip Transition

Abstract

This paper reports the design of 220–270 GHz probe type waveguide to microstrip transition on Quartz and LTCC substrates, which acts as an initial step towards the development of receiver front end at sub-millimeter-wave frequencies. For Quartz substrate the transition shows a simulated return loss better than 10 dB and insertion loss less than 1 dB, while for LTCC substrate the simulated return loss is better than 11dB and insertion loss is less than 0.6dB in back to back configuration.
