Abstract :
Ortho-mode transducers (OMTs) are key components in both dual-polarized antenna feed systems for telecommunication and radio-astronomy applications. The evaluation of the overall system performance requires the measurement of the return loss, isolation and cross-coupling levels of the OMTs. In this paper a novel technique for the microwave measurements of the full 4 × 4 scattering matrizx of such devices is reported, which is based on different measurements at the single-polarized ports.
