Abstract (en)

A shaped radiation pattern antenna is provided, suitable for generating relatively wide angle radiation fields, having a shaped dielectric lens attached to a conducting mounting plate, a waveguide assembly arranged to inject a signal into the dielectric lens through an aperture in the mounting plate and a portion of radiation absorbent material disposed between the mounting plate and the dielectric lens and arranged such that, in use, effects arising from internal reflections on the power profile of emitted radiation from the lens are reduced.
