Abstract

The design of a dielectric resonator notch filter utilizing an experimental composition of dielectric material pellet at microwave frequencies is proposed. In this paper, an electrical model of a dielectric resonator filter is designed and fabricated utilizing a new dielectric material composition variation. Recent advances and designs in dielectric resonator structures have shown the advantages of using various dielectric materials types and shapes in microwave devices which yield different microwave characteristics. Thus, the design of this dielectric resonator filter that incorporates the experimental type of dielectric ceramic material will present the feasibility and performance of the filter design and dielectric material. The design will first be designed and simulated in microwave simulation software and the final design will be fabricated into a working prototype..
