Low Permittivity

Double layer and edge-location via techniques are combined for electromagnetic band gap (EBG) size reduction. The study of the required number of elements and their dimensions is carried out in order to suppress the surface wave propagation modes and consequently to reduce the mutual coupling between radiating elements in low-permittivity substrates. By applying these techniques, the size of the EBG mushroom is reduced by 30%; however, the bandwidth operation maintains its value, and these structures can be integrated between radiating elements in broad bandwidth antennas.

Simulation Results

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.
