Abstract
A multi-band antenna includes a reflector that provides a ground plane, a first array of first radiating elements, each of the first radiating elements located on a front side of the reflector and configured to emit first electromagnetic radiation in a low frequency band, a second array of second radiating elements, each of the second radiating elements located on the front side of the reflector and configured to emit second electromagnetic radiation in a high frequency band, and an artificial magnetic conductor (AMC) plane that is located between the reflector and a radiator of the first radiating element and between the reflector and a radiator of the second radiating element. The AMC plane is configured to reflect the first electromagnetic radiation substantially in phase and to reflect the second electromagnetic radiation substantially in antiphase.
