Compact Branch Line Coupler with Rectangular Defected Ground Structure (DGS) for 6G

Abstract

This Article presents a Compact Branch Line Coupler operating at 95 GHz using FR4 substrate εr = 3.4 for Radar Applications with Rectangular Defected ground structure at the Ground Layer using ADS tool .The Designed Coupler exhibits , The Return Loss (S11), Insertion Loss (S21), Coupling Factor (S31), Isolation Value (S14) . The proposed DGS design confers size reduction because of the shift of the operating frequency to higher values. Key Words: Defected Ground Structure, Compact Branch Line Coupler
