Abstract :
A coplanar waveguide with ground (CPWG) to dielectric ridge waveguide (DRW) transition is proposed and investigated. The proposed transition consists of two parts for the analysis, and they are the CPWG to Microstrip line transition and the Microstrip line to DRW transition. The mechanism of the transition and the electromagnetic (EM) field distributions are given in this paper. Attenuation analysis´s of the DRW, CPWG, and CPW are presented in this paper. With full-wave EM simulation, the insertion loss of a back-to-back transition is around 5 dB at 0.3THz.
