Abstract

The miniaturization of small antenna Q has been discussed in this article. The Q can be expressed as a Rayleigh quotient, which is a linear functional of the current distribution on the antenna. By minimizing the Rayleigh quotient, a generalized eigenvalue equation can be obtained. The smallest eigenvalue gives the minimum possible quality factor for a specified antenna structure, and the corresponding eigenvector is the optimized current distribution that renders the Q minimum for the specified antenna geometry.
小型天线的小型化
本文讨论了小天线Q的小型化问题。Q可以表示为瑞利商,它是天线上电流分布的线性泛函。通过最小化瑞利商,可以得到一个广义特征值方程。最小特征值给出了特定天线结构的最小可能质量因子,相应的特征向量是优化的电流分布,该分布呈现了特定天线几何形状的Q最小值。
