Problems solved by technology

Different frequency dual polarization and variable polarization functions can be realized through a reflector antenna and an electric variable polarization feed. This technology is mature, but it cannot meet the requirements of most applications in terms of height and mechanical characteristics. Require

For the low-profile mobile satellite communication system composed of flat-panel antennas, since the polarization axis is fixedly connected to the antenna aperture, adjusting the polarization by rotating the antenna obviously does not reduce the height.
