Aperture antenna

Aperture antenna, also known as waveguide antenna, is a type of antenna which is specially designed for electromagnetic waves in a waveguide, with the concept of plane wave which is applied on its aperture. The waveguide interacts with the plane wave, which is then converted into the far-field radiation pattern. In comparison to the traditional antennas, the aperture antenna can capture a maximum amount of signals within its active region, resulting in the capacity to acquire a much wider bandwidth in comparison with the traditional antenna designs.

The aperture antenna can be used in the direction finders, radar systems and communication systems. In the direction finders, it can be used as a tool to determine the direction of a signal, while in the radar systems, it can be used to send and detect the signals. In the communication systems, the aperture antenna which is arranged in certain patterns can be used to enhance the transmission of the signals in close quarters.

In conclusion, the aperture antennas can be used in various applications, from direction finding to communication, due to their wide bandwidth. With the ability to both send and receive the signals, the aperture antenna can be a useful tool for almost any situation when it comes to applications of the signals.
