In this proposed antenna, mushroom type EBG structures are used for suppressing the surface waves. These structures are periodic metallic patches, which are connected to the ground plane with vias. The most important characteristic of the EBG structure is their stop band frequency. By the help of this stop band, the surface waves of the proposed antenna are suppressed. Thus by the suppression of surface waves, the bandwidth of microstrip antenna is improved at same operating frequency from 9.6% to 15.5% i.e 5.9%.

“…Due to the capability of these structures for reducing the surface waves, they can improve the antenna performance. This improvement can be achieved in reduction of back-lobe radiation, increasing the antenna gain and increasing the antenna efficiency [7]. Different forms of EBG structures such as mushroom-like EBG structure or dielectric rods and holes are studied and evaluated their capability to reduce mutual coupling effect.…”

An important issue in antenna array design is reduction of mutual coupling. In square microstrip antennas this reduction can be achieved by using electromagnetic band-gap (EBG) structures. They can help in the reduction of mutual coupling by using their capability of suppressing surface waves propagation in a given frequency range. In this paper, we analyze the isolation properties of different EBG structures are compare them in antennas arrays by simulations. A new configuration of a planar compact electromagnetic bandgap structure is investigated. Compared to the conventional EBG (mushroom structure), a size reduction of 67.2% is achieved. Simulation results show that a significant value of mutual coupling reduction, more than 6 dB, can be obtained by using the proposed structure.Index Terms----Electromagnetic-bandgap (EBG), mutual coupling, structures, microstrip antenna arrays, surface wave.

“…Several broadband EBG structures were found in the literature. Typically, there have been two approaches aiming to obtain EBG structures with wider bandwidth: the use of EBGs with via-holes [5] (with the inconveniences of complex and expensive manufacturing process) and the adoption of multilayered FSSs over a metallic ground plane or multiperiod mushroom-like structure [6] (which yields less compact designs and is rather expensive). Recent research efforts focus on the development of planar EBG that does not need vias and that can be integrated antenna to enhance the gain and reduce the backward radiation and increasing efficiency [7][8][9].…”

A novel electromagnetic bandgap (EBG) structural design based on Fractal geometry is presented in this paper. These Fractals, which are the Sierpinski triangles, are arranged to repeat each 60° to produce the hexagonal unit cells. By changing the gap between two adjacent Sierpinski triangles inside EBG unit cell, we can produce two EBG structures separately that have broadband and dual bandgap. By using the suspending microtrip method, two arrays 3 × 4 of EBG unit cells are utilized to investigate the bandgap of the EBG structures. The EBG operation bandwidth of the broadband structure is about 87% and of the dual-band structure is about 40% and 35% at the center bandgap frequencies, respectively. Moreover, a comparison between the broadband EBG and the conventional mushroom-like EBG has been done. Experimental results of the proposed design show good agreement in comparison with simulation results.
