Design of SIW Bandpass filter using DGS-DMS technique for 5G applications

Banu priya A, Umma Habiba H

Abstract


A novel SIW bandpass filter based on the combination of DGS (Defected Ground Structure) and DMS (Defected Microstrip structure) is proposed. Their excellent defected characteristics are verified through the simulated results. The proposed filter is designed by etching a dumbbell shaped DGS in the ground plane of the SIW cavity in order to improve the stopband performance. Defected Microstrip structure (DMS) is made by etching a single or double slots to create a finite passband, rejection band and slow wave characteristics. The filter is fed using microstrip to SIW transition technique over a material with dielectric constant of 3.5 and thickness of 0.5mm. Additionally to a sharp cutoff, the filter exhibits simple design, low insertion loss of 0.5dB and it achieves rejection bandwidth with overall 28dB attenuation from 26GHz to 28GHz. Utilizing this concept, SIW BPF of 27.4GHz center frequency with 7.2%fractional bandwidth at -3dB has been implemented for the application of 5G spectrum bands. The structure has been simulated using Advanced Design Software (ADS).
