  1. Antenna

    An antenna is an electrical device which converts electric power into radio waves, and vice versa. It is usually used with a radio transmitter or radio receiver. In transmission, a radio transmitter supplies an oscillating radio frequency electric current to the antenna's terminals, and the antenna radiates the energy from the current as electromagnetic waves. In reception, an antenna intercepts some of the power of an electromagnetic wave in order to produce a tiny voltage at its terminals, that is applied to a receiver to be amplified. Antennas are essential components of all equipment that uses radio. They are used in systems such as radio broadcasting, broadcast television, two-way radio, communications receivers, radar, cell phones, and satellite communications, as well as other devices such as garage door openers, wireless microphones, bluetooth enabled devices, wireless computer networks, baby monitors, and RFID tags on merchandise. Typically an antenna consists of an arrangement of metallic conductors, electrically connected to the receiver or transmitter. An oscillating current of electrons forced through the antenna by a transmitter will create an oscillating magnetic field around the antenna elements, while the charge of the electrons also creates an oscillating electric field along the elements. These time-varying fields, when created in the proper proportions, radiate away from the antenna into space as a moving transverse electromagnetic field wave. Conversely, during reception, the oscillating electric and magnetic fields of an incoming radio wave exert force on the electrons in the antenna elements, causing them to move back and forth, creating oscillating currents in the antenna.

Examples of antenna in a Sentence

  1. Joe Ottaviano:

  2. Saptarshi Bandyopadhyay:

    Radio telescopes on Earth can not see cosmic radio waves at about 33 feet( 10 meters) or longer because of our ionosphere, so there's a whole region of the universe that we simply can not see, but previous ideas of building a radio antenna on the Moon have been very resource intensive and complicated, so we were compelled to come up with something different.

  3. Emirates President Tim Clark:

    We were not aware that the power of the antennas in the United States [ has ] been doubled compared to what's going on elsewhere. We were not aware that the antenna themselves have been put into a vertical position rather than a slight slanting position, so on that basis we took that decision late last night to suspend all our services until we had clarity.

  4. Hugh Elliott:

    Miracles You do not have to look for them. They are there, 24 7, beaming like radio waves all around you. Put up the antenna, turn up the volume - snap... crackle... this just in, every person you talk to is a chance to change the world...
