Twist and Glide Symmetries for Helix Antenna Design and Miniaturization

Twist and Glide Symmetries for Helix Antenna Design and Miniaturization

Here we propose the use of twist and glide symmetries to increase the equivalent refractive index in a helical guiding structure. Twist- and glide-symmetrical distributions are created with corrugations placed at both sides of a helical strip. Combined twist-and glide-symmetrical helical unit cells...
