Theory construction and realization of an extremely small antenna

本文建立了一种计算具有任意形状结构的极小天线特性的理论方法，并推导出沿天线导体方向电流的积分方程。这个方程的核不包括导数和积分的计算，从而导致易于处理和减少计算时间。将积分方程应用于螺旋结构，并采用矩量法求解。在此基础上，实现了一个极小的螺旋天线。

A theoretical method for calculating the characteristics of an extremely small antenna with an arbitrarily shaped structure has been established, where an integral equation is formulated for the current along the antenna conductor. The kernel of this equation does not include calculations of derivatives and integrations, thereby leading to easy treatment with a reduced computation time. The integral equation has been applied to a spiral structure and solved using the method of moments. Based on the obtained results, an extremely small spiral antenna has been realized.
