Artificial magnetic conductor based circularly polarized crossed-dipole antennas -- part II: AMC-structure without grounding pins

Editors’ Highlight—

This paper describes the use of the TM surface waves of an artificial magnetic conductor (AMC) / high-impedance surfaces periodic structure to extend the circularly polarized (CP) bandwidth of a crossed dipole antenna. The authors compare experimental results with simulation results. They discuss the extra resonances and CP radiation from AMC structures without grounding pins. The effect of the AMC size is a particularly interesting discussion
