E, H and J field Variation in H-Plane Horn Antenna when EBG unit Cell is placed inside the Wave Guide

 Abstract— In this paper we design H-plane horn antenna working in ionization band. The idea is to analyze the E,H and J-field distribution in the wave guide and then the same is conducted by making the H-plane part unchanged we place three unit cells of EBG's in the wave guide part. And the unit cell consists of cylinder pin organized in a two-dimensional lattice pin have inner side of wave guide at one side and the square patch at other side which is inside the wave guide . here the surface waves from EBG cells will affect the space waves or propagating wave in antenna thus it will change EM wave propagation in the horn antenna. To illustrate this in this paper the E,H and J-field distributions are analyzed. Results are compared and presented in this paper.
