In-phase reflection and band-gap characteristics of EBG structure for millimeter-wave applications
Nov 16, 2016
Design and analysis of millimeter-wave (MMW) mushroom-like, circular-patch electromagnetic band-gap (EBG) structure is presented. The in-phase reflection and band-gap characteristics of the proposed EBG structure are investigated. Results show that the proposed EBG structure has stable reflection properties when normally and obliquely illuminated by a plane wave with different polarizations around the 60 GHz band. In addition, the proposed EBG structure is found to have a band-gap around the same frequency bandwidth. With these properties, proposed EBG structure is suitable to be used as reflectors in antenna applications in orderto increase the gain and improve the radiation characteristics.
