Abstract
The properties of helical aerials have been investigated between 26.5 GHz and 40 GHz. Beamwidths and polarisations are given as functions of helix parameters and frequency. With a suitable choice of dimensions, helixes can be used successfully as broadband feeds for parabolic reflectors and lenses at millimetre wavelengths.
