The generation and reception of variable-polarized signals becomes more and more mature, and this provides a basic for the development of polarization-related technology. Polarization is usually applied in radar, fiber with good channel environment, and with the in-depth study of polarization channel, also widely used in the complex wireless communication, thus spawning many new theories such as polarization modulation, polarization spectrum sensing, polarization multiplexing, and polarization filters. The main applications of polarization in radio propagation are explored, the latest theoretical results of polarization research in wireless communication summarized, and the future development direction also discussed in detail.
