Antennenarrays

Antennenarrays are a type of antenna system used to focus and direct electromagnetic waves. They consist of multiple individual antennas, typically arranged in a particular configuration, to achieve a specific radiation pattern or to increase the overall gain of the system.

The basic principle behind an antennenarray is to combine the signals from multiple antennas in such a

Antennenarrays can be categorized into different types, depending on the configuration of the antennas and the
