<p>Disclosed is an antenna provided with a radiation means and an individual power-feed means. The radiation means includes a pair of columnar radiators using reactance elements. The individual power-feed means branches at a signal feed point and includes a pair of power-feed branches that feed power individually to the radiators in the radiation means. The impedances of the radiators and the lengths of the power-feed branches are set such that, for a signal with a preset frequency (wavelength ?), the impedance between the signal feed point and one radiator is conjugate to the impedance between the signal feed point and the other radiator.</p> |
