Summary :

A mode transformer between the NRD guide and the vertical strip line was developed and applied to the right angle corner, T-junction, and 3-port junction at 60 GHz. Emphasis was placed on a fully CAD-based design procedure by using an electromagnetic field simulator. Agreement between the simulated and measured performances of the junction circuit was obtained, and thus the validity of the design procedure was confirmed. A well-balanced transmission coefficient of the 3-port junction, found to be 4 0.5 dB, was observed in the bandwidth of 2 GHz around a center frequency of 60 GHz.
