Radio Frequency Antennas: Advances and Applications Kevin Merriman

Radio frequency antennas are the interface between electric currents moving in metal conductors and radio waves propagating through space. During transmission, a radio transmitter provides an electric current to the antenna's terminals, and the antenna releases the energy from the current as radio signals. During reception, an antenna picks some of the power of a radio wave in order to create an electric current at its terminals, which is transferred to a receiver to be amplified. Antennas are indispensable components of all radio equipment. It is a collection of conductors, linked electrically to the receiver or transmitter. This book traces the progress of radio frequency antennas and highlights some of their key concepts and applications. It strives to provide a fair idea about this discipline and to help develop a better understanding of the latest advances within this field. This book is a vital tool for all researching or studying radio antennas as it gives incredible insights into emerging trends and concepts.
