Antennas are widely used in modern communication and broadcasting products such as cellular phones, satellite television, terrestrial television, radios, radar, and numerous other applications. Antennas are passive devices that convert electrical current to and from electromagnetic waves. Antennas are used in connection with transmitters and receivers for radiating electromagnetic waves into or receiving electromagnetic waves from space. The electromagnetic wave is typically used to carry some sort of signal which can be decoded to result in usable data. An antenna's gain (ratio of the intensity of an antenna's radiation pattern) is based on its directivity and efficiency (lack of dissipative losses). Directivity is an antenna's ability to focus energy in a desired direction. Antennas are typically directional which requires specific mounting criteria in order to receive maximum energy from a signal. A parabolic antenna is a directional antenna used for radio, television and data communications. Parabolic antennas are typically dish-like antennas intended for satellite communication and broadcast reception, space communications, radio astronomy, and radar. An omnidirectional antenna radiates maximum power equally in all directions. A yagi antenna is an antenna made up of an array of a dipole and reflectors (signal reflecting elements).
