Design of a Novel EBG Structure for Antenna Arrays

Abstract:

EBG structures can greatly reduce mutual coupling effects between patch antennas by suppressing surface wave propagation in a specified frequency range. A two-annular rectangular slot EBG structure is proposed and its performance is analyzed. HFSS simulation results show that mutual coupling loss in a 2x2 patches system is reduced appreciably (10dB in the work frequency band 19.6~22GHz (K/Ka band)) compared with antenna without EBG structures. What’s more, the side effects on other performances, like reflection parameter and bandwidth, are so little that can be neglected. With this EBG structure loaded in antenna array, the systematic performance can also be improved.
