Abstract :
A single arm spiral printed on a grounded dielectric substrate is designed using a genetic algorithm with Pareto ranking of a 2D search plane, with dual objectives of a unity axial ratio and a boresight main lobe. The antenna is shown to be efficient with good circular polarisation over a useful bandwidth
