Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a multifunctional circular polarization converter array based on a multi-layer FSS structure and a wireless communication system. Background technique [0002] At present, the commonly used existing technologies in the industry are as follows: In wireless communication systems, circularly polarized antennas are favored because of their advantages in resisting interference from rain, snow, clouds and fog, and being able to send and receive electromagnetic waves with arbitrary polarization. As a microwave device that can convert the linearly polarized electromagnetic waves of the feed antenna into circularly polarized electromagnetic waves, the circular polarization converter is well adapted to the needs of various communication antenna systems. In recent years, various forms of circular polarization converters have been designed and widely used in commun...

Problems solved by technology

[0004] Although the existing FSS circular polarization converter technology has been widely used, with the increasing intelligence and integration of wireless communication systems, remote communication systems urgently require an FSS circular polarization converter capable of collecting reflection The function of the type FSS circular polarization converter and the transmission type FSS circular polarization converter are integrated to realize the flexible regulation of the polarization conversion direction, so that the circular polarizer can be applied to many different communication technology occasions at the same time, but It is very difficult to achieve this requirement through existing method technology

[0005] To sum up, the problems existing in the existing technology are: the function of the traditional FSS circular polarization converter is relatively single and solidified, and can only realize unidirectional polarization conversion. Once the type of FSS adopted is determined, the corresponding polarization conversion direction then it was determined

The technical defects caused by the traditional FSS circular polarization converter are: the function is single and solidified, the flexible adjustment of the polarization conversion direction cannot be realized, and it cannot be applied to multiple communication technology occasions at the same time
