With the rapid advancement of wireless communication technology, the necessity for multi-band mobile devices is increasing. So the reconfigurable antenna is an excellent option for wireless communications. The reconfigurable antenna has favorable properties such as compact size, similar radiation performance, and less co-site interference as compared to traditional designs. This paper proposed and discusses a reconfigurable monopole antenna with dimensions 75×75mm2 on an electromagnetic bandgap (EBG) using graphene material. Monopole antenna operates at 5 GHz, which is loaded by EBG, and the intended EBG provides a bandgap in the range of frequency from 4 to 9.8 GHz. A coaxial cable feeds the monopole antenna, which is connected to the inner wire. A single monopole denotes matching bandwidth from 4.6GHz to 5.3GHz, with a gain of 8 dBi. Graphene material is used to achieve a reconfigurable beam between four monopole antennas. The beam is switching toward the direction of biasing monopole, four monopole antenna structure is proposed and offers 7.8 dBi constant gain in all four beam directions and the same reflection coefficient, band.
