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.
