Abstract

A novel antenna design method is proposed and applied to overcome the narrowband characteristics of the monopole antenna by loading it with lumped elements. A genetic algorithm based optimization technique is used to determine the load values, their respective locations and the matching network elements. A bandwidth ratio of 20:1 within the frequency range of 23-460 MHz is achieved with a 2 meter long loaded monopole antenna, and by electronically switching three different matching networks a bandwidth ratio of 64:1 is obtained between 15 MHz to 960 MHz.
