【摘要】 构建了一种紧凑结构的分形倒L天线,用矩量法对天线的阻抗特性、辐射方向图特性和天线电流分布作分析研究,并进行实验验证。结果表明,分形倒L天线不仅大大降低了天线的高度,而且有效地缩减了天线的水平长度,是天线小型化设计的重要方法。更多还原

【Abstract】 A novel compact fractal inverted-L antenna is presented. The antenna impedance characteristics, radiation patterns and current distribution are analyzed by employing the method of moments. The simulation results and measured data show that the antenna has excellent performances with lower resonant frequency and shorter overall height and horizontal length.更多还原
