Radio Frequency Antennas Advances and Applications by 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,Read More
