Abstract
An apparatus, for example a multi-band radio frequency antenna system, comprising: a primary reflector, for example a parabolic reflector; and a near-field feed arrangement comprising: a multi-band waveguide feed comprising a first waveguide feed for a first frequency band and a second waveguide feed for a second frequency band separate to the first frequency band, wherein the first waveguide feed and the second waveguide feed are co-axial and have, respectively, a first aperture and a second aperture; and a splashplate located within the near-field of the first waveguide feed, located within the near field of the second waveguide feed and configured as a feed for the primary reflector.
