Radiation of Electromagnetic Waves by Dipole with Variable Radius along Antenna Length

An approximate analytical approach to the problem of electromagnetic wave radiation by a dipole (or monopole) antenna with a longitudinally varying radius is presented. The solution was carried out using generalized method of induced electromotive forces (EMF). A systematic numerical analysis is performed to assess the influence of radial variation on the antenna’s electrodynamic properties. The analytical findings are subsequently corroborated through comparison with experimental observations.
