Mutual Coupling Reduction Between Large Antenna Arrays Using Electromagnetic Bandgap (EBG) Structures

Abstract

Electromagnetic bandgap (EBG) structure has been using to mutual coupling reduction between antennas. Different to the former applications between single antennas (even in array), here the EBG structure has been used between large antenna arrays, which are composed of many antenna elements. These antenna arrays could be used as transmitting and receiving antennas in radar and communication systems where high isolation is expected between transmission and reception.
