Integral Equation Formulation to Radiation Problem from Phased Array Slots Antenna

Abstract

An electric field integral equation (EFIE) is used to formulate the radiation problems from conducting bodies of revolution (BoR) with aid of Method of Moments (MoM) as a numerical solution to reduced the three-dimensional problems to a two dimensional problems.In this paper phased array of slots antenna mounted on the body of revolution is analyzed to study the effect of the number of elements (slots) on the radiation pattern. Phase shift between elements of spacing 0.5 is applied to make the beam maximum is steered.The formulation above give us the results agree with theoretical formula, therefore, one can treat such problems numerical with efficient results.
