Compact EBG Structure for Alleviating Mutual Coupling Between Patch Antenna Array Elements

The periodic structure like Electromagnetic Band Gap (EBG) is a hot research topic in the academia and RF-microwave industry due to their extraordinary surface wave suppression property. This paper involved in designing a compact uni-planar type EBG structure for a 2.4GHz resonant frequency band. Double folded bend metallic connecting lines are successfully utilized to realize a low frequency structure while a size reduction of 61% is achieved compared to the theoretically calculated size. From the transmission response, the Surface Wave Band Gap (SWBG) is found to be 1.2GHz (1.91-3.11GHz) whereas the Artificial Magnetic Conductor (AMC) characteristic is observed at 3.3GHz.
