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: An antenna device, an array of antenna devices, and a base station having an antenna device. A radiator is configured to radiate an electromagnetic signal in a direction parallel to a radiating axis of the antenna device. The radiator has a substantially planar shape perpendicular to the radiating axis and a resonant structure adjacent to the radiator. The resonant structure has a substantially planar shape parallel to the radiator, wherein the radiator is configured to radiate the electromagnetic signal in a first frequency band and the resonant structure is configured to have a resonant frequency within the first frequency band.
