CS 556 Mobile Communications. Fall 2008. Timothy John Adams. Introduction. Antennas used for mobile communications and other applications. 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.. by Mike Denko, Alex Motalleb, and Tony Qian . Image taken from: http://findicons.com/icon/84804/wifi. Purpose.

An electronic device that is used either for radiating electromagnetic energy into space or for collecting electromagnetic energy for space. Any wire carrying AC current will radiate electromagnetic waves and an electromagnetic wave will induce a voltage in a length of wire. for Small and Large Lots. Small antennas.
