Abstract : In this note we discuss a technique for defining the geometry of a dipole antenna such that low-frequency parameters of the antenna, such as capacitance and mean charge separation distance, are readily calculable. This technique involves the assumption of an appropriate static charge distribution which we call an equivalent-charge distribution. Calculating the potential distribution from the equivalent charge one then chooses two appropriate equipotential surfaces as surfaces for the antenna conductors. With the antenna surfaces so chosen the static potential distribution for the antenna is known. Other parameters, such as the antenna charge and dipole moment, are calculated as integrals over the assumed equivalent-charge distribution.
