Dipole antennas are resonant for the frequency of design. Its resonance frequency is dependent on its length which is a function of the wavelength of operation. Dipoles are usually designed for half the wavelength of its frequency of operation. Hence every dipole has its own resonance frequency of operation and to vary it is difficult. In this paper the author proposes a technique of adding two small circular rings to the elements of the dipoles. Varying the position of the ring shifts its resonance frequency. This type of dipole is very useful for operation over a band of frequencies than at single frequency and is not expensive.
