| Summary: | Ortho-mode transducers (OMTs) are key components in antenna feed systems when dual polarizations are involved, such as satellite communication, remote-sensing applications, radio astronomy, and astrophysical observations of the cosmic microwave background. Typically, they are used to receive dual-polarized signals from a horn antenna and separate them into two independent single-polarized channels. With the development of modern communication systems, it is preferred to process dual-polarized signals over a wide band or multiple bands. However, the design theory of OMTs is not well-developed, and most OMTs are designed by experience and full-wave optimizations. |
