An antenna is a device that transmits and receives electromagnetic waves. Simply put, it converts electrical signals into radio waves (when transmitting) and vice versa (when receiving). Antennas are used in a wide variety of applications, such as mobile networks, radio, television, Wi-Fi, satellites, and even radar systems.
Radar is a system that uses radio waves or microwaves to detect the presence, location, and speed of objects. Radars are used in a variety of fields, including defense, meteorology, air traffic control, and even autonomous vehicles.
