Antenna is a vital (important) component of any wireless communication system. Also we cannot think of wireless communication without antenna. Understanding background concept will help in designing new versatile antennas. An antenna is a metallic conductor system capable of radiating and collecting EM energy. EM wave is the oscillation of electromagnetic (EM) field. An antenna is a device to transmit and/or receive electromagnetic waves. Electromagnetic waves are often referred to as radio waves. An antenna must be tuned (matched) to the same frequency band as the radio system to which it is connected, otherwise reception and/or transmission will be impaired.
Radio Wave Propagation
EM waves are cobination of Electric and Magnetic waves. Propagation means how radio waves travel from one point to another
