Abstract

A multi-band artificial magnetic conductor (AMC) is described wherein N capacitive frequency selective surfaces (FSS) are employed to realize a zero degree reflection phase at N non-harmonically related resonant frequencies. A simple Cauer Type I LC network is proposed to model the plane wave reflection coefficient for this type of multi-band AMC. As an example, a dual band AMC (N=2) is fabricated and tested to demonstrate the concept. Both a reflection phase resonance and a surface wave bandgap are demonstrated in the GSM 850 MHz band and the PCS 1900 MHz band.
