双锥天线的普遍模型

双锥天线的普遍模型

内容简介：椭圆双锥天线是具有普遍性的物理模型。应用坐标变换和共形变换研究椭圆双锥天线，在传输纯TEM波的假设下，把无限长椭圆双锥结构变换为二维平面结构，从而得到椭圆双锥天线输入阻抗闭合解，其典型结果与文献一致。所给出的椭圆双锥天线有关公式可以用来分析许多类型的锥天线，包括非对称锥天线。

Abstract：The methods of coordinate transformation and conformal mappingare applied to study the problem of radiation from a bi-conical antenna with elliptic cross section. The infinite elliptic cone geometry can be transformed into the two-dimensional plane under the assumption of pure TEM spherical waves. The closed-form solutions for the characteristic parameters are obtained. The antenna studied is a universal model which can be used to analyse many type of conical antennas including asymmetrical ones.
