Abstract :
A novel method for computing the input impedance and induced currents on cylindrical antenna structures is investigated. This technique considers the antenna when placed between two parallel ground planes, thus allowing the use of cylindrical harmonic Fourier expansions to represent the fields. Enforcement of boundary and continuity conditions on the tangential field components results in solutions for the discrete spectral coefficients of these expansions. Convergence is discussed and computational validations are presented for varied cases
