Abstract

This paper presents the study of the new exciting method for improving gain of the conventional conical horn at C-band frequency by using mushroom-like Electromagnetic Band Gap (EBG). The important technique of this paper is to use the basic mushroom-like Electromagnetic Band Gap (EBG) on circular plate and connected to waveguide/coaxial adapter. From the study, we found that such technique can provide the better gain and small size when compare to the conventional conical horn antenna. From the simulated results by using the licensed Computational Simulation Software (CST), we found that this technique provides the gain around 19.3 dBi.
