摘要：

The side lobe effects cause the wastage of energy in antenna arrays. In this work, two types of electromagnetic band-gaps (EBGs) are used to diminish the side lobes in 2 x 2 Patch Antenna Array at 6 GHz through mushroom-like EBG and triple side slotted (TSS) EBG (TSSEBG). The proposed EBGs are placed on the top surface of the antenna array to eliminate undesired surface currents. The connecting vias in TSSEBG compared with the mushroom-like EBG structure is decreased from 392 to 92. Accordingly, an easy way in fabrication is guaranteed. The TSSEBG provided triple band gaps of frequencies compared with the structure of mushroom-like EBG that only had one. The TSSEBG is placed in a flexible structure, which is suitable for antenna applications. The compact EBG and TSSEBG antenna arrays respectively demonstrate 13.77 and 14.68 dB gain, 14.2 and 15.3 dBi directivity, -24 and - 28.5 dB side lobe, and 90.5% and 87% efficiency at the operating frequency of 6 GHz.
