Abstract :
A new EBG structure is designed and introduced in this paper, and its radiation properties such as reflection phase and band gap area are presented. Also this new EBG structure is compared with a usual Mushroom-like EBG structure. Both of these EBG structures have a substrate with same size and same material. But the new EBG structure is designed with a new patch shape and also there is no connecting via between its ground plane and patch, contrary to Mushroom-Like EBG structure. First, we designed a usual Mushroom-like EBG, then a new type of EBG structure is designed and employed to increase the gain of the antenna. At the end, it was resulted that the gain of antenna has increased noticeably by using the EBG structures. We used Ansoft HFSS software to simulate the antenna and EBG structures.
