Abstract: An antenna device for transmitting or receiving a radio frequency (RF) signal. The antenna device includes a plurality of RF signal feeds, and an array of M times N radiating elements. The array includes M rows and N columns, where M≥2 and N≥M. The array is subdivided into a plurality of clusters. Each cluster includes one or more radiating elements. The one or more radiating elements of each cluster are connected to one of the RF signal feeds. The columns of the array include two outer columns and one or more inner columns, where each inner column includes K1 clusters, where K1≥1. Each outer column includes K2 clusters, where K2>K1.

Abstract: The present disclosure relates to multiband antenna apparatuses. An example multiband antenna apparatus includes a first dipole radiating element, a second radiating element, and a metasurface superstrate (MSS) structure. The first dipole radiating element may be configured to operate at a first frequency band and arranged on an upper plane of a support structure in a first distance to a reflector plate. The second radiating element may be configured to operate at a second frequency band and arranged on a lower plane of the support structure in a second distance to the reflector plate. The second distance is smaller than the first distance. The second frequency band is higher than the first frequency band. The MSS structure is arranged in an area inside arms of the first dipole radiating element and enhances a performance of the second radiating element.
