Abstract:
1. A method for producing with a dipole antenna electromagnetic radiation in a desired direction over a wide range of wavelengths, comprising: exciting with a radio frequency signal first and second elongated conductive radiating elements of a dipole antenna having a combined overall length l to produce an oscillating time varying electric current within the first and second elongated conductive radiating elements; selectively varying said radio frequency signal to have any wavelength λ within a pattern wavelength range of said antenna extending from about 0.5l to at least about 2.0l; and selectively controlling a current distribution along a length of said first and second elongated conductive radiating elements to form, at any wavelength selected within said pattern wavelength range, an antenna radiation pattern having a peak in a direction substantially orthogonal to a length of said elongated conductive radiating elements.
