Design and Analysis of Monopole Antenna with two layered EBGS at One side

Abstract: EBG structures are drawing lot of interest in electromagnetic and antenna research these are compact in size. So the idea to use this EBG structures in patch antennas is good and in this paper we illustrate the Two layered EBG usage on monopole antenna. This EBG are designed and analysed in many shapes for different purposes. This structures will manipulate the antenna parameters and alter them according to the designer to improve the conventional antenna parameters to reach the requirements of new technologies. The EBG have periodic metal plates on metal pin vias. The gap between the plates have capacitance and metal pin exhibits inductance these C and L together makes EBG’s as high impedance electromagnetic surfaces. This EBG presence will reduce the surface wave propagation and enhance the antenna general parameters.
