Reject Region are investigated for a proposed structure of square shaped mushroom. The radiation
characteristics of monopole antenna over this 2D-EBG is tested by considering two cases. During first
case monopole antenna is made to operate within band rejection region. Second case monopole antenna
made operate outside the band rejection range. The obtained results during first case is showing
enhancement in operating band width and smoother radiation pattern. In second case the effect is null and
2D-EBG resembles like conventional plane reflector. The simulated results are presented.

There may be some obstacles between the source and the destination which cause diffraction, reflection, scattering and attenuation. There are some types of obstacles such as knife edge, wedges and round edges. This paper shows the diffraction loss caused by wedges based on Uniformal Theory of Diffraction (UTD) given in using Matlab software. It could be said that this is an important method because radio waves travel over wedge shaped roofs of buildings and corners of the buildings. In addition this diffraction loss changes for both roofs and corners for a particular obstruction material. Furthermore, the electrical properties of the wedge shaped obstacles are affecting the diffraction loss such as conductivity and dielectric constant. The result shows that higher conductivity leads to have a higher amplitude oscillation at the receiver.
