Simulation Analysis of a Strip Dipole Excited Electromagnetic Band-Gap (EBG) Structure
Abstract
The design of an Electromagnetic Band-Gap (EBG) for a particular antenna application is described and investigated in detail through simulation. The typical design parameters, analytical models, and numerical methods for EBG design are summarized. Discussion is provided on interpretation of the EBG reflection coefficient phase for antenna applications and on the range of the EBG bandwidth. It is determined for antenna applications that the reflection phase and current design methods may be misleading. Instead, it is opinioned and shown that the phase of the scattered near fields at the EBG surface is more applicable to characterizing the EBG for antenna applications. A new set of design parameters is presented that will allow an engineer to design an EBG with relative accuracy. The impact of a dielectric substrate, vias, and number of unit cells is also demonstrated.
