ring antenna

ring antenna

A radio telescope consisting of many small elements arranged in a ring. For example, the RATAN 600 ring antenna is a multiplate reflector composed of reflecting panels that are adjusted to form part of a paraboloid surface with its axis directed at the source under observation. An advantage of the ring antenna over other shapes is that its side-lobe responses have no preferred direction and are small and widely distributed.
