Abstract :
The design of a printed eccentric spiral antenna optimised for 3G nomadic devices such as personal data assistants is discussed. An optimum chromosome selection method for chromosomes that constitute points on a Pareto surface of 3 dimensions is used in a genetic algorithm (GA). The GA is used with a method of moments (MoM) technique and small populations of less than 25 and seeks to synthesize a single arm spiral antenna suitable for use at UMTS, GSM1800 and GSM900 frequencies. Two Pareto ranking algorithms are explored and their resulting Pareto optimal chromosome sets compared using a novel false Pareto vector magnitude metric. A suggested strategy for optimisation of triband antennas using a GA is presented
