Abstract
Disclosed is a conically shaped reflector for producing dual polarized electromagnetic radiation in a surface wave transmission system. The reflector includes a circular conductive region that covers the apex of the conical reflector with the surface wave transmission line being joined to the center of the circular conductive region. Extending outwardly from equally spaced apart positions along the circumference of the circular conductive region are four conductive log-periodic arms.
