    • A novel design of high frequency hidden hand-held antenna which includes two metal arms above a lower arm of finite ground plane. By properly choosing the lengths of these arms and the separations between them, the bandwidth can be broadened more than 20%. Thus, it is suitable for personal mobile communication applications. A full wave equivalent circuit analytic model is also developed to analyze and optimize the geometrical configuration including the lengths and separations between the arms. Numerical analyses for current distribution on the conductor surface and various antenna characteristics such as input impedance and radiation patterns are computed by the use of the analytical models. Experimental results and numerical computations all confirm that better performance characteristics including broadened antenna bandwidth are achieved by this novel antenna.
    • 高频隐藏式手持天线的新颖设计,包括有限接地平面下臂上方的两个金属臂。 通过适当选择这些武器的长度和它们之间的距离,带宽可以扩大20%以上。 因此,适用于个人移动通信应用。 还开发了全波等效电路分析模型来分析和优化包括臂之间的长度和间隔的几何配置。 通过使用分析模型计算导体表面电流分布和各种天线特性(如输入阻抗和辐射图)的数值分析。 实验结果和数值计算都证实,这种新型天线可以实现更好的性能特征,包括增宽的天线带宽。
