A Frequency Independent Twisted Wave Front Constant Beamwidth Lens Antenna.
Abstract
A frequency independent constant beamwidth lens antenna concept is described. The device may be configured in various ways such as with a cylindrical lens with a retina. The essential feature is that a twisted planar or hyperbolic paraboloidal phase or wave front is formed by the antenna which then in turn produces a frequency independent constant beamwidth beam in the far field of the antenna. Moreover, the frequency independent constant beamwidth beam may be steered or scanned in azimuth without moving the lens.
