Mutual Coupling Reduction in Microstrip Antennas by Using Dual Layer Uniplanar Compact EBG (UCEBG) Structure
Electromagnetic band-gap (EBG) structures can serve in the reduction of mutual coupling by using their capability of suppressing surface waves propagation in a given frequency range. In this paper, a dual layer uni-planar compact EBG (UC-EBG) structure is analyzed and its dispersion diagram is extracted using the commercial finite element full wave solver High Frequency Structure Simulation (HFSS). This UCEBG structure can be built using planar fabrication technique without any modification. The dual layer UC-EBG structure, having a lower resonant frequency than the single layer one, is inserted between Eplane coupled microstrip antenna arrays to reduce the mutual coupling. This method has been verified by the HFSS simulations and as a result, a significant 17 dB mutual coupling reduction is noticed from the simulations.
