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. 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.

2. Raz Itzhaki Tamir:

   Currently, if an antenna is not perfect, you have to live with it, with the losses, we can change that and be flexible, thus gaining more revenue from the satellite.

3. Ericsson Networks:

   In addition to broadening Ericsson's portfolio of antenna and filter products, the acquisition will bring vital competence for the evolution of advanced radio network products.

4. Fiona Hill:

   I did not feel Alexander Vindman had the political antenna to deal with something that is straying into domestic politics. Not everyone is suited for that, that does not mean in any way that I was questioning Alexander Vindman overall judgment, nor I was questioning in any way Alexander Vindman substantive expertise. Alexander Vindman is excellent on issues related to Ukraine, Belarus, and Moldova, on Russian defense issues.

5. Joe Ottaviano:

   SEWIP is the Navy’s continued push to keep electronic warfare excellence ahead of the threat. It is an incremental set of upgrades to the SLQ-32 which was designed in the late 70s and deployed in the 80s. It gives the Navy the ability to upgrade and outpace the threat. It provides the ability to quickly upgrade processing as new threats come online and become more complex without overhauling the antenna.
