ADAPTIVE BEAMFORMING AND CANCELLATION OF JAMMER USING LINEAR ARRAY ANTENNA SYSTEM
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 2015, Vol 4, Issue 4
Abstract
The radiation pattern of an antenna depends on the type, size and parameters of feed current. To change the direction of maximum and minimum gain the mechanical steering is necessary. Electronic steering is only possible in array antenna system with adaptive feed current system. Relative magnitude of feed currents, relative phases or separation between antenna elements, geometric shape of the array are responsible for the overall radiation pattern. Another popular technique of analysis of antenna parameters using Rao-Wilton-Glisson (RWG) edge elements consists of pair of dipole of triangular shape. In this paper we will observe the impact of antenna parameters on the shape of radiation pattern of both linear and rectangular array using the concept of conventional antenna engineering and RWG approach.
