Performance Design and Optimization Analysis of High-Performance Communication Components in Complex Electromagnetic Environment

Power transmission and transformation equipment is often in a complex electromagnetic environment, the transmission of image, video, point cloud and other data is faced with the problem of limited bandwidth and low transmission efficiency, a novel three-band frequency selective surface structure with high stability is proposed, which provides three stable resonant frequency bands, expands the coverage of the transmission frequency band, realizes reliable transmission of 5G frequency band suppressing electromagnetic interference of other frequencies, further improves communication rate. The proposed structure achieves excellent miniaturization characteristics, has a small size of 0.072λx0.072λ. In addition, the proposed structure has stable filtering characteristics as different polarized electromagnetic waves are incident at different angles, and implements good out-of-band suppression characteristics and low insertion losses, it has a good application prospect in the field of high-quality transmission of images and video and point clouds.
