An antenna array (or array antenna) is, much like it sounds, several elements interconnected and arranged in a regular structure to form an individual antenna. The purpose of an array is to produce radiation patterns that have certain desirable characteristics that a single element would not. A stacked dipole array, as shown in

point at which it is fed) the 1- λ loop will show a small gain over a 1/2-λ dipole. Theoretically, this gain is about 2 dB, and measurements have confirmed that it is of this order. The 1-λ loop is more frequently used as an element of a directive antenna array (the quad and

The antenna array is necessary to overcome the low antenna gain due to the short wavelength of the millimeter-wave. The array antenna results in beamforming. The beamformer is introduced to control the phase and the amplitude of each element of the array. Refer to the diagram below, three different architectures for the 5G phased array are ...
