• Radiation Pattern of Antenna; • Polarization of Antenna; • Intensity of Radiation; • Effective Aperture; • Gain & Directivity; • Bandwidth; • Power Gain & Radiation Efficiency; • Effective Length; • Input Impedance. The Antenna, also called Aerial, component of radio, television, and radar systems that directs incoming and outgoing radio waves. Antennas are usually metal and have a wide variety of configurations, from the mastlike devices employed for radio and television broadcasting to the large parabolic reflectors used to receive satellite signals and the radio waves generated by distant astronomical objects.
