Abstract

This work investigates a novel design approach for creating an independently tunable dual-band electromagnetic bandgap (EBG) surface for a use as an artificial magnetic conductor (AMC). The EBG geometry consists of two reactively loaded concentric square loops. The outer loop is used to tune for the first resonance, while the inner loop is used to tune the second resonance. The resonance frequency of each loop is independent of the other and can be tuned down in frequency with capacitors and up in frequency with inductors.
