Thin-wire transmission lines and dipoles, whose diameters are much less than the operating wavelength, carry currents which are essentially sinusoidal in form. Moreover, the electromagnetic field radiated by the filamentary (a to infinity ) straight

The authors consider a center-fed solid circular cylindrical dipole radiating in a circular waveguide terminated in infinite ground planes. Numerical results show how the input admittance depends on the dipole length, feed gap width, and waveguide ra

The author consider a strip dipole with an assumed current density on its surface and uses the Poynting vector method to determine the complex power leaving the surface. This makes it possible to obtain the input impedance at the dipole's infinitesim
