Reduction of EMI and Mutual Coupling in Array Antennas by Using DGS and AMC Structures
Considering the difficulty of via construction in EBG structures and the cost of lossy materials and absorbers, in this paper, we look for implementing DGS and Artificial Mag-netic Conductor to reduce mutual coupling in enclosures and array antennas particularly in CBS antennas. Circular ring defected ground structure and capacitive loaded AMC strips are de-signed and optimized to have electromagnetic band gaps and incident wave reflection features, respectively, in the resonant frequency band of cavity backed slot (CBS) antenna. The complete structure consists of CBS antenna with circular ring DGS and CLS-AMC. These structures are investigated and enhancement in EMI and the radiation patterns of this antenna is observed.
