Summary:
Recently, a great deal of diversity has emerged in mobile phone handsets with respect to the design and functionality. Since the antenna characteristics generally vary based on the target functionality of the handset, it is difficult to construct antennas that always satisfy the design requirements for multi-type usage. To overcome this difficulty, this paper proposes a novel parallel calculation algorithm employing the genetic algorithm for multi-type antennas. The key technique in the proposed algorithm is to reuse the final solution of one type of antenna as the first population of the other type antenna. There are two forms of the proposed algorithm, a simple one and a functionalized one. These algorithms are applied to the automatic design of a compact multi-band antenna for clamshell type handsets used in the closed and open positions (types). The results show the final antenna constructed using the proposed algorithm achieves the required design conditions for both the open and closed types.
