Abstract
An electromagnetic bandgap material is electrically attached to an edge, and enables high isolation between antennas due to the attenuation of surface waves. The disclosed embodiments further provide narrow reactive edge treatments in the form of artificial magnetic conductors (AMCs) whose physical width is less than 1/10 of a free space wavelength for the frequency of surface currents intended to be suppressed. These embodiments still further provide several AMCs suitable for this purpose, along with several exemplary manufacturing techniques for the AMCs.
