三角形偶极子天线的瞬态辐射研究

A Study of a Transient Radiation of a Trilateral Dipole Antenna

主要研究了一种三角形偶极子天线在空间的瞬态辐射问题 ,从对偶极子的标量位和矢量位的计算入手 ,运用叠加原理 ,得出了该三角形偶极子天线的辐射场和辐射功率 ,并与赫兹偶极子、扇形偶极子的结果进行了比较 ,通过实测和使用 ,证明该天线是一种较好的超宽带天线。

In this paper,the transient radiation in space of a trilateral dipole antenna is mainly analyzed It starts with the scalar and vector potential calculation of the Hertz dipole The superposition theorem is employed in obtaining the radiation fields and power of this trilateral dipole antenna ,which then are compared with the results of Hertz dipoles and fan-shaped dipoles It has proved in the practical test and use that this antenna is a good ultra wide-band one
