Dynamically-Tunable EBG Structure Demonstrator

Abstract

Electromagnetic Bandgap (EBG) structures exhibit large continuous regions as a function of frequency over which they will not allow a signal to propagate. A subclass of bandstop filters (BSF), EBG structures "stop" a signal from passing through by having signals not propagate in abeyance of Maxwell's Equations. Typically, EBG performance is achieved by modulating the geometric properties of an electromagnetic-guided or radiating structure so as to create a periodicity which induces the EBG and as such is not tuneable if implemented as integrated circuits (IC) or printed circuit boards (PCB). This work implements dynamic tuning by using RF/microwave switches to move the effective ground plane of a guided structure.
