Abstract :
This paper presents a study of the technique to enhance the gain of horn antenna by using Electromagnetic Band Gap (EBG) transfer the power from its aperture through EBG structures. The proposed antenna has the advantages of low profile, low cost for fabrication, and light weight. Moreover, it provides the moderately high gain. A Computer Simulation Technology (CST) software has been used to compute the reflection coefficient (S11), VSWR, radiation patterns, and gain of the antenna. The bandwidth, at S11 (-10 dB), is between 10 to 14 GHz with a gain of 24 dB at 12 GHz.
