Abstract
A waveguide-type dielectric filter suitable for wideband filter applications made of a metallized dielectric material is provided. The filter includes two or more mutually coupled resonators disposed in a longitudinal manner. The coupling between adjacent resonators is provided and adjusted by slots or through holes. The dielectric block is covered with metal ground coating with the exception of an uncoated area at the input and output that creates two contact pads on one surface of the dielectric block that are electrically isolated from the metal ground coating. Metallized blind holes are formed on the opposing surface of the dielectric block with respect to the contact pads. These blind holes effectively move the ground plane closer to the contact pad, which, in turn increases the coupling between the input and output resonators and external circuitry, which is essential for building wide bandwidth band pass filters.
