A wideband waveguide-to-multilayer-PCB-microstrip transition for millimetre wave measurement applications

A wideband waveguide-to-microstrip transition is introduced. The microstrip line is made on a multilayer PCB that makes it suitable to be used for the measurement of the integrated millimetre wave transceivers. Moreover, the extra layers make it possible to design the transition for wide bandwidths more than 40 percent.
