Directional Antenna
A directional antenna is a type of antenna that radiates or receives greater power in specific directions, allowing for increased performance in communication systems. In space and astronautical engineering, directional antennas are commonly used in satellite communication systems, where they are used to transmit and receive signals to and from specific locations on Earth. They are also used in spacecraft communication systems, where they are used to communicate with Earth-based stations and other spacecraft. Directional antennas are preferred over omnidirectional antennas in space and astronautical engineering because they provide higher gain, longer range, and better signal-to-noise ratio. They are also used in radar systems for tracking and monitoring objects in space.
