Abstract:
A mould method used in polarized wire grid fabrication is proposed. The grids with analytical and computer simulation analysis method is designed. A variety of specifications, different aperture and grid frame materials for microwave/millimeter wave band used the mould method is produced. This series of polarized wire grid is tested by the liquid nitrogen environment, mechanical and electrical performance test. The results show that the polarized wire grid has strong environment adaptability, high mechanical precision and excellent electrical performance, and can meet the demand of practical application, which develop a new method for millimeter wave polarized wire grids localization.
