Abstract
A succinct method is proposed for deriving spectral representation of the fringe capacitances of horizontal and vertical frills. The approach enables fast and accurate calculation of the input admittances of coaxial-fed antennas. The importance of the fringe capacitance calculation for magnetic frill sources is demonstrated by a variational formulation. Simple formulas are also provided for extracting fringe capacitances of frills with different wire radii and frill widths.
