要約

An approximate mathematical model has been constructed for a small compared to wavelength asymmetrical dipole antenna loaded by metal disks of unequal diameters at both ends of the dipole. In proximity of the first low-frequency resonance, the current amplitude at the feed point and the input impedance are presented versus frequency for a dipole antenna and for a disk top-loaded stub antenna mounted on a finite-size base.
