| description | The invention provides a dielectric waveguide filter. The dielectric waveguide filter comprises at least three interconnected dielectric waveguide resonant cavities and metallized blind holes. There are at least one row of metallized blind holes, and each row has at least two metallized blind holes. The periodically arranged metallized blind holes and the metallized top surface of the dielectric waveguide filter form an artificial magnetizer structure. The artificial magnetizer structure is an electromagnetic band gap structure, in a stop band of the electromagnetic band gap structure, electromagnetic waves can be attenuated exponentially through the metallized blind holes arranged periodically, and in other words, the stop band of the electromagnetic band gap structure can hinder propagation of the electromagnetic waves. For the metallized blind holes arranged periodically, the electric field is distributed between the metallized blind holes and the metal top surface of the dielectricwaveguide filter, so tha |
