What is an Antenna Array?

An antenna array is a collection of antennas that work together to focus radio waves in a particular direction. Antenna arrays are used in a variety of applications, including radar, communications, and navigation.

In a 5G system, an antenna array can be used to focus radio waves in a particular direction, allowing for more efficient communication and higher data rates. 5G systems are expected to use higher frequencies than previous generations of cellular networks, making it even more important to have an efficient way to focus the radio waves.
