Abstract

This paper presents a broadband dual-mode microwave filter suitable for mobile communications. The Conductor loaded dielectric resonator filter reported in [5] is used as the basic building block for these devices. A simple input coupling configuration is introduced to improve the filter bandwidth significantly with less than half of the physical volume of TEM filters and good electrical performance. The basic properties of this resonator have been studied using a finite element method electromagnetic software (HFSS). Fundamental design rules for broadband bandpass filters have been presented. A two-pole bandpass filter was designed, fabricated and measured to verify the proposed approach.
