The practical aspects of paraboloid aerial design

The paper gives a short account of the technique of designing paraboloid and other forms of point-fed double-curvature aerials. The general properties of such aerials with their advantages and limitations are described; the requirements for the feed are discussed, and illustrated by reference to all the main types of feed that have been used. Some purely practical points such as reflector tolerances and the design of supporting members are dealt with. Special applications such as the provision of ¿split¿ feeds, and the production of shaped patterns for various purposes are also described. A bibliography of all the important British papers on the subject is appended.
