Combining electric and magnetic dipoles in the construction of antennas
Keywords:electric dipole, magnetic dipole, wideband antennas, electromagnetic field
AbstractIt was shown that for antenna bandwidth extending insufficient to use electric or magnetic dipoles separately. As was proved experimentally that the combination of electric dipoles with magnetic dipoles enable to attain antenna bandwidth increasing more than two octave. Using the example of a combination of electric radiators it is shown that the matching band can be extended to the low-frequency region. The design of an electrically small ultra-wide band antenna is proposed. The dimensions of the antennas do not exceed 1/5 of the frequency wave length. The antenna directional patterns in the main planes are close to the cardioid.
