Antennas used for mobile communications and other applications. Name: . Mashhour. . j. umah. ID:202322165. Welcome . What is an antenna?. An antenna is an . electrical conductor or system of conductors used for transmission and reception of electromagnetic . waves. By: James VE3BUX. Definition. The Modern Dictionary of Electronics defines an antenna as:. That portion, usually wires or rods, of a radio transmitter or receiver station used for radiating waves into or receiving them from space. It changes electrical currents into electromagnetic waves, and vice versa.. Typically the diameter of the ground plane should be at least 3.. λ. /4. The parameters of helical antenna are-. D- diameter of a turn on the helix antenna.. C- circumference of a turn on the helix antenna.. Feedline. Maintenance and Improvements.
