A novel transition structure between microstrip line and surface mounted dielectric foam waveguide is presented. The waveguide flange is ended by a cavity and allows a fully automated assembly onto an RF printed circuit board (PCB) in order to minimize high volume production cost of millimeter-wave products. The new concept has been applied for the integration of two waveguide filters, presenting respectively a Chebyshev and a pseudo-elliptic response, and that can be surface-mounted in a transmission chain of a VSAT system operating in the [29.5-30.0] GHz band.
