Abstract

In this paper a multiband dielectric resonator with array of defect at the ground plane is proposed. Filter is constructed by placing high-quality factor 〖TE〗_01δ mode dielectric resonators on the microstripline. The focus is on the design process includes choosing optimum geometry of a dielectric resonator so that high Q can be achieved. This is designed without compromising miniaturization and efficiency. It is observed that the integration of dielectric resonator with DGS may be merged to achieve wide band.Two band with 6 GHz low pass filter and 2 GHz band pass filter has been achieved. The filter which is proposed for microwave communication is expected to have better quality factor compared to lumped elements-based BPF. The used MBDRF have bandwidth of 6GHz and 2 GHz with dielectric constant of 60±1.
