Abstract

In this paper, a new pattern of Electromagnetic Band Gap (EBG) structure is introduced on the substrate of microstrip patch antenna to enhance the gain and bandwidth. This proposed antenna works at the frequency of 2.3GHz which is for S band communication. The proposed antenna is designed on a FR-4 substrate which has the thickness of 1.6mm. The double L shaped EBG structures are introduced on the substrate in order to improve the gain and bandwidth of the conventional antenna. The proposed antenna is fabricated and its results are compared. It seems that the fabricated results have good agreement with the simulated one, also the gain and bandwidth are increased.
