Problems solved by technology
The traditional polarization converter has low conversion efficiency, only applies to a single electromagnetic wave incident direction, complex structure, and thick thickness, which cannot meet the requirements of low distortion, wide adaptability, and low profile of the current communication system, and reduces the effectiveness and integration of the communication system. Therefore, it is more and more important to design a high-efficiency polarization conversion device suitable for any incident direction of electromagnetic energy. The present invention utilizes an artificial electromagnetic structure to make a polarization converter, which overcomes the above-mentioned defects
