Using genetic algorithms to develop a conformal VHF antenna

Abstract: This master thesis describes the design simulation of a conformal antenna for the 88-108MHz Very high frequency (VHF) broadcast audio frequency-modulation (FM) band. The antenna is intended to t in the 　at area inside the head-band of an over ear hearing-protector headset. The space for the antenna is limited by an existing head-band design, where the unused internal area is the space studied in this thesis. A genetic algorithm is described for the multiple objective optimization of the antenna matching and radiation pattern optimization. The results of multiple genetic algorithm evaluations are described, and possible further improvements outlined. Progress is made on the development of the antenna. The antenna radiation pattern is evolved in desirable way, but a di-culty in solving the antenna matching problem is identied. Proposals for resolving the antenna matching problem is described in the final section.
