1. A multi-band antenna, including:
a reflector, which provides a ground plane;
a first array of first radiating elements, each of the first radiating elements being 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 being located on a front side of the reflector and configured to emit second electromagnetic radiation in a high frequency band; and
an artificial magnetic conductor (“AMC”) plane, which 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,
wherein the AMC plane is configured to reflect the first electromagnetic radiation substantially in phase and to reflect the second electromagnetic radiation substantially in antiphase.
