A novel F-shaped hybrid isolator is proposed to reduce mutual coupling between two horizontally polarized X-band Tx/Rx microstrip antennas. The proposed configuration is composed of EBG-mushroom structure and two F-shaped metallic walls on both sides of EBG structure. The EBG-mushroom structure is designed for suppressing the surface wave propagation between the Tx/Rx antennas. The novelty of the F-shaped metal wall lies in its improvement of antenna radiation characteristics. The isolation level and radiation pattern performance of the Tx/Rx antennas with the hybrid isolator is simulated and compared to other isolation methods applied. The obtained result shows a maximum increase of 44.4dB in the isolation level, and main lobe direction is modified, comparing with original Tx/Rx antennas.
