A fully metallic glide-symmetric waveguide filter with transmission in Ka-band and attenuation at its second harmonic is proposed. The filter is low-loss and cost-effective for high frequencies, and it can be easily integrated with an antenna. Glide symmetry and the possibility of breaking this symmetry provide an additional degree of freedom for passband and stopband control. A new kind of 2-D glide symmetry, referred to as braided glide symmetry, is presented, showing an increased attenuation per unit cell.

适用于毫米波频率 5G 的多孔滑移对称滤波器


提出了一种全金属滑动对称波导滤波器，其在Ka波段传输并在其二次谐波处衰减。该滤波器对于高频而言损耗低且经济高效，并且可以轻松与天线集成。滑移对称性和打破这种对称性的可能性为通带和阻带控制提供了额外的自由度。提出了一种新型的二维滑移对称性，称为编织滑移对称性，显示出每晶胞的衰减增加。
