Antennas

Antennas are devices designed to transmit or receive electromagnetic waves, facilitating wireless communication. They convert electrical signals into electromagnetic waves for transmission or vice versa. Various types, such as dipole, yagi, and patch antennas, cater to different frequencies and applications. Their design involves optimizing size, shape, and elements to achieve desired radiation patterns and gain. Antennas play a crucial role in diverse fields, including telecommunications, radar systems, and satellite communication, enabling the efficient exchange of information wirelessly. Advanced technologies, like phased-array antennas and metamaterials, continue to enhance performance, enabling more robust and high-speed wireless connectivity.
