A simple programming technique (MATLAB) has been written for the analysis of a beam reconfigurable antenna array. The technique is based on the calculation of mutual impedance using Induced EMF method. This can be applied to an array of dipoles arranged in various configurations. An array of 12 dipoles has been positioned at the edge of a cube structure to demonstrate this behaviour. The size of the...
In this article, Differential Evolution (DE) algorithm has been used to design a non-uniformly spaced collinear dipole array of uniformly optimized length. The goal is to generate a pencil beam in the horizontal plane with minimum Standing Wave Ratio (SWR) and fixed Side Lobe Level (SLL). Dynamic Range Ratio (DRR) of current amplitude distribution is kept at a fixed value. A simultaneous optimization...
