Emerging wireless, space and satellite communication links require light weight, low loss, temperature stable and inexpensive communication devices. Microwave filters are the key element of any communication system or microwave link. Microwave filters are usually implemented by using waveguide, coaxial, microstrip or lumped element resonators. Only dielectric resonator filters provide best combination of volume versus insertion loss of filter. Dielectric resonator filters offer very high Q factors to provide lowest pass band insertion loss and higher selectivity with compactness and minimal power requirements. And satisfy vital demand of emerging space communication systems and cellular industry by offering very high-quality factor due to their inherent low loss material. This paper describes basic steps to design dielectric resonator filter with the help of a 3D finite-element method (FEM) simulation tool, Ansoft HFSS (High Frequency Structure Simulator). Dielectric disks are used to tune the filter response within a limited range.
