Radiation pattern shaping for broadcasting collinear antenna array using Invasive Weed Optimization

Abstract

A novel method using the Invasive Weed Optimization to optimize the geometry of a collinear antenna array is presented. The goal of the optimization is to produce an antenna array geometry with a specified shape for its radiation pattern, so that reception across a designated service area is uniform. The antenna array is designed for FM radio or DVB-T TV broadcasting applications, however, this kind of optimization can be applied to other antenna
