摘要

提出了一种用于手持终端移动卫星通信的双线螺旋天线。分析了将Altshuler(1997)提出的改良折叠偶极子天线固定在金属体上所获得的天线特性。本文报道了指向性和阻抗。给出了改进的折叠偶极子天线的结构和尺寸。计算了金属本体尺寸发生各种变化的情况。结果表明，随着金属体体积的增大，其对天顶方向的方向性影响不大。得到了全向辐射方向图。

Characteristics of handheld terminal a modified folded dipole antenna for mobile communication

The article proposes a bifilar helical antenna for handheld terminal mobile satellite communications. The antenna characteristics obtained due to fixing the modified folded dipole antenna, proposed by Altshuler (1997), to the metal body was analyzed. In this paper, the directivity and impedance is reported. The structure of the modified folded dipole antenna and its dimensions are shown. The case in which the dimension of the metal body was variously changed was calculated. It was proven to have little effect on the directionality in the zenith direction, when the volume of the metal body increases. The omnidirectional radiation pattern was also obtained.
