Antenna
In space and astronautical engineering, an antenna is a device used to transmit and/or receive electromagnetic waves. Antennas are crucial components of spacecraft communication systems, as they allow for the transmission of data and commands between the spacecraft and ground stations. Antennas can be designed for specific frequencies and polarizations, and can be either directional or omnidirectional. They can also be deployed in a variety of ways, such as fixed or deployable, depending on the mission requirements. Antennas can be affected by various factors in space, such as radiation, temperature, and micrometeoroids, which can degrade their performance over time.
