Abstract :
A novel transition structure between microstrip line and surface mounted dielectric foam or plastic waveguide is presented. The waveguide flange is ended by a cavity and allows a fully automated assembly process onto an RF printed circuit board (PCB), in order to minimize mass-production cost of millimeter-wave products. The new concept has been applied for waveguide filter integration, presenting respectively a Chebyshev and a pseudo-elliptical response. Such surface mounted devices are specified for VSAT systems, operating in the 29.5-30.0GHz band.
