Abstract

A compact multi antenna system with DGS (Defective Ground Structure) for ECM (Electronic Countermeasure) applications is proposed in this paper. Two monopoles are located on the opposite corners of the PCB and spaced 10 mm apart by a small ground portion. To decrease the mutual coupling caused by near-field two monopoles are decoupled by using the metal strip. The proposed Wang-shaped DGS of size 30mm*16mm is placed in ground plane. It does provide a method to improve antenna performance. In this way, performance parameters with S11 ≤ -10 dB and S21 ≤ -18dB at resonance frequency 6.18 GHz are achieved. The analysis has been done by using IE3D software based on MOM (Method of Moments).
