Implementation of Circular Waveguide Band Pass Filter using Artificial Dielectric Resonator for Transverse Electric Propagation Mode

Waveguide is capable of working at high frequencies. The addition of a resonator to the waveguide can adjust the working frequency as desired without changing the dimensions of the waveguide. In this research, circular waveguide band pass filter was made using an artificial dielectric material as the resonator. Artificial dielectric material is a material that is not available in nature, this material is made by combining small particles of conductor with dielectric material. The response of this artificial dielectric material after becoming a resonator can change the working frequency and adjust according to the propagation mode we want. In this research, a band pass filter is made with electric transfer propagation mode. Determination of this mode affects the design of the dielectric resonator that is made so that a filter with return loss and bandwidth parameters is obtained.
