Crossed dipoles fed with a turnstile network

A "turnstile network" is introduced which may be conveniently used for circ ular polarization synthesis. The network, outfitted with proper phasing stu bs, forms a balanced quadrature hybrid; for an antenna with less than a per fect reflection coefficient, the reflected power will appear at an isolated port, which may be terminated, resulting in good polarization properties c oupled with good input voltage standing wave ratio. A crossed-dipole array is used as a test-bed to demonstrate the turnstile network.
