Band Gap Calculation for Two Layered Perfect Conductor (PEC) Electromagnetic Band Gap Structure in Application of Microstrip

摘要

The object of this paper is to calculate the band gap energy of the newly designed waveguide structure. The structure used was 2 layers of perfect conductor (PEC) sandwiched with an electromagnetic band gap (EBG) or photonic crystals (PC) in the center. The lattice arrangement of the EBG was square lattice. The cylinder rods is made of PEC also and separated with each other at 1mm. The size of the cylinder is 0.43mm in radius. The cylinder rods were embedded in FR-4 which has dielectric constant 4.9. We designed the structure and simulate it in CST Microwave Studio (MWS). We performed a parametric phase sweep in eigenmode. The band energy was studied and analyzed.
