—Mutual coupling is a critical issue in compact
array design and reducing this is one of the main efforts in
Microstrip antenna array design. Periodic structures can help
in this situation by suppressing surface wave propagation in a
given frequency range. The purpose of this work is to show the
viability of using 2D EBG structures to this aim. This paper
presents a double element Microstrip antenna array inserted
with the EBG structures like conventional mushroom,
Jerusalem cross slot and slot loaded EBGs around 5-6 GHz.
The performances are compared for mutual coupling
reduction. Simulated results verify the improvement in
performance of the antenna array compared to the array
antenna without EBG. The slot loaded EBG is found to be
good showing a 5.8dB mutual coupling reduction.
