It is a result of coherent combining of multiple signals, either from multiple transmitters or from multiple receivers.
Although “array” as discussed here applies to generic MIMO systems, it is best illustrated by using two scenarios—single-input multiple-output (SIMO) and multiple-input. Each antenna in an array is called an element antenna (or simply an element). The elements in an array can be the same or different.
In most practical cases, they are identical in construction (with different feedings). Configuration of arrays: Linear (1D), planar (2D), and conformal (3D).

Beamforming or spatial filtering is a signal processing technique used in sensor arrays for directional signal transmission or reception.
This is achieved by combining elements in an antenna array in such a way that signals at particular angles experience constructive interference while others experience destructive interference. Beamforming can be used at both the transmitting and receiving. An antenna array (often called a ' phased array ') is a set of 2 or more antennas.
The signals from the antennas are combined or processed in order to achieve improved performance over that of a single antenna. The antenna array can be used to: To understand antenna arrays and phased arrays, navigate through the following pages. The aim of this book is to provide a coherent account of the theory, analysis, and design of these antennas, as well as The pattern of a dipole can be modiﬁed by placing a passive or parasitic Fig.
