Application of the planar I/O terminal to dual mode dielectric waveguide filters

Planar I/O terminals have been applied to dual-mode dielectric waveguide filters. Two types of the filter, for Ku-band 13 GHz and K-band 22 GHz were designed and fabricated only by metal plating on the surfaces of a ceramic block. They are realized with very small volumes of less than 0.05 cc.
