A circularly-polarized corner reflector antenna

Unidirectional, circularly-polarized radiation may be obtained by tilting a dipole in a corner reflector. Inherent advantages of this antenna are the simplicity of both the construction and adjustment. The theory of images is employed to develop the basic theory of the antenna for the cases of greatest practical interest. An experimental investigation has been made on the radiation characteristics of a practical-sized antenna as a function of its geometric parameters. From this data, an antenna producing unidirectional, circularly-polarized radiation has been designed and constructed.
