TLDR
In this paper, a novel electromagnetic band gap (EBG) surface has been introduced by some modifications in conventional mushroom-like EBG structure which has more compact electrical dimensions to reduce the mutual coupling loss.Abstract:
The design of more than one antenna system called antenna arrays. Patch antenna arrays are used extensively due to their high directivity and gain, also light weight and low cost. In antenna arrays energy is wasted in backward radiation as well as losses due to mutual coupling. Placing of elements close to each other can minimize the overall size of an array. On the other hand, a major drawback of this type of antenna arrays is mutual coupling; that depends on the separation between the elements, causes unfavorable effects on antenna characteristics. The use of Electromagnetic Band Gap structures, also called photonic band gap (PBG) structures in the antenna arrays can limit the coupling by suppressing the surface waves. In this paper, a novel electromagnetic band gap (EBG) surface has been introduced by some modifications in conventional mushroom-like EBG structure which has more compact electrical dimensions. This structure is proposed to be placed in between four patch arrays antennas to reduce the mutual coupling loss. The investigation included E coupling direction, and antennas array system is analyzed using CST mws. A significant value of −27.036 dB mutual coupling reduction is reached at 5.8 GHz resonant frequency.read more
