A concave reflector is shaped to receive energy emanating from a signal source positioned at the reflector's vertex and to reflect all received energy in a uniform output direction. The reflector additionally introduces a designated constant phase shift into all reflected energy relative to unreflected energy from the signal source, regardless of where the received energy impinges upon the reflector. When the source signal is periodic, this reflector design minimizes near field interference between the reflected signals, since they all have the same phase shift relative to the unreflected source signal. Furthermore, if the reflector is designed to implement zero phase shift, reflected and non-reflected signals tend to combine additively in the far field, focusing most of the transmitted energy toward the center of the transmission pattern. In addition to this reflector apparatus, other features include a process of manufacturing a signal reflector, a product formed by this manufacturing process, and beam shaping process incorporating these principles.
