Abstract :
The design and theory of a passive microwave polarization adaptor (PA) for very small aperture terminal (VSAT) use are described. The PA changes two orthogonally polarized signals into two copolarized signals. The PA consists of two filters, a twisted waveguide, an orthomode transducer, a transition adaptor, and a 90-degree waveguide bend. A prototype has been designed with an insertion loss of -0.5 dB and return loss of -18 dB. Test results for the device are given.<>
