EBG Frequency Response Tuning Using an Adjustable Air-Gap

By Mehdi Veysi and Meisam Shafaee
Progress In Electromagnetics Research Letters, Vol. 19, 31-39, 2010


A new adjustable Electromagnetic Band-Gap (EBG) structure whose frequency response is controllable by adjusting spacer height is proposed. The finite difference time domain method is adopted for the simulations. Results show that the desired frequency response can be selected by adjusting the spacer height. The effects of the air-gap on the polarization dependent and conventional EBG structures have been investigated both theoretically and numerically. The agreement between the theoretical calculations and numerical results is reasonably good.
