1. A multiband antenna apparatus, comprising:
a first dipole radiating element configured to operate at a first frequency band and arranged at a first distance to a reflector plate,
a second radiating element configured to operate at a second frequency band and arranged at a second distance to the reflector plate, the second distance being smaller than the first distance, and the second frequency band being higher than the first frequency band,
a third radiating element configured to operate at a third frequency band higher than the second frequency band, the third radiating element being arranged at a third distance to the reflector plate, and the third distance being smaller than the second distance, and
a metasurface superstrate (MSS) structure arranged in an area inside arms of the first dipole radiating element, the MSS structure being configured to enhance performance of the second radiating element and the third radiating element.
