Radiation Efficiency Theory

Radiation efficiency theory explains how effectively an antenna converts input power into radio waves that radiate into space. It considers factors like material properties, design, and losses within the antenna, which can absorb or dissipate energy instead of radiating it. High efficiency means more of the input power is emitted as useful signals, while low efficiency indicates more power is lost as heat or other forms of energy. This understanding helps engineers design antennas that maximize performance for communication, broadcasting, or radar systems, ensuring minimal power wastage and clearer signal transmission.
