近来，各种无线应用已经变得非常流行。特别地，诸如移动的电话的移动的终端正在被积极地开发。在移动的终端的发展中，天线的小型化和多频带是非常重要的问题。然而，在小型天线的设计中，还没有合理的设计策略。因此，天线的发展取决于电磁模拟器或工程师的能力。并且为了获得所需的特性，需要许多尝试性的工艺。这造成了许多问题，如延长发展。因此，目前，利用遗传算法进行天线自动设计的技术受到了广泛的关注。提出了一种基于遗传算法染色体长度运算的天线小型化设计策略。所提出的设计技术提供了保持天线特性所需的最小面积。并且，天线的有效小型化和在设计战神中去除许多不期望的导体是可能的。去除不需要的导体提供了天线的低成本设计。这种新的设计方法可以成为天线小型化的合理设计策略。
Recently, various wireless applications have hugely become popular. Especially, mobile terminals such as mobile phones are actively developed. In developments of mobile terminals, miniaturization and frequency multiband of antennas are very important issues. However, there are no rational design strategy in small antenna designs. So, antenna developments depends on electromagnetic simulators or capability of engineer. And many cut-and-try processes are necessary for achieving desired characteristic. This makes many problems such as prolongation of developments. Then, now, automatic design techniques of antenna using genetic algorithm (GA) are paid attention. In this paper, the new design strategy for miniaturization of antennas is proposed by operation of chromosome-length in GA. Proposed design technique provides a minimum area necessary for keeping characteristics of a antenna. And, efficient miniaturization of a antenna and removing many undesirable conductors in a design ares are possible. Removing undesirable conductors provides lower-cost designing of antennas. The new design method can become rational design strategy for antennas miniaturization.
