Abstract : Analytical approximations have been developed to compute the capacitance of electrically small tubular monopole antennas. The expressions developed are algebraically simple, facilitating manual calculations and rapid iteration of designs when used in a computer program. Plots are given of the accuracy of previous expressions and the approximations developed herein as a function of the arguments. It is shown that the approximations are sufficiently accurate, making them useful as tools to aid in the design of electrically short cylindrical monopoles over a wide range of heights, lengths, and diameters.
