Glide Symmetry to Improve the Bandgap Operation of Periodic Microstrip Defected Ground Structures

摘要

A novel one-dimensional periodic planar defected ground structure exploiting glide symmetry is proposed here. The planar structure is designed to operate as an electromagnetic bandgap structure that avoids the use of vias. Simulation results show that the glide-symmetric structure offers a wider rejection bandwidth as well as a higher rejection level than the conventional structure (without glide symmetry). Measurement results of the fabricated prototypes are provided to verify the simulation results.
