Holey Glide-Symmetric Filters for 5G at Millimeter-Wave Frequencies

A fully metallic glide-symmetric waveguide filter with transmission in <inline-formula> <tex-math notation="LaTeX">$Ka$ </tex-math></inline-formula>-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.
