摘要：
A prototype tuneable planar electromagnetic bandgap filter has been developed for implementing a voltage-controlled bandwidth, intended for adaptive spectral control. A tuneable single-cell defect that allows tuning of the bandwidth is introduced into the structure using monolithic microwave integrated circuit technology. A combination of three-dimensional electromagnetic modelling of the planar structure and equivalent circuit modelling techniques is presented to validate this work. The simulation and measured results are in very close agreement.
