Antenna Array
Antenna array is a set of multiple antennas that are arranged in a specific pattern to achieve a desired radiation pattern. Antenna arrays are used in various applications such as satellite communication, radar systems, and deep space exploration. The main advantage of using antenna arrays is that they can provide higher gain, directivity, and signal-to-noise ratio compared to a single antenna. Antenna arrays can be classified into two types: uniform and non-uniform. Uniform arrays have identical antennas with equal spacing between them, while non-uniform arrays have different antennas with varying spacing between them. The performance of an antenna array depends on various factors such as the number of antennas, their spacing, and the type of array used.
