Microwave antenna



A microwave antenna is a physical transmission device used to broadcast microwave transmissions between two or more locations. In addition to broadcasting, antennas are also used in radar, radio astronomy and electronic warfare.

Uses

 * One-way (e.g. television broadcasting) and two-way telecommunication using communications satellites
 * Terrestrial microwave relay links in telecommunications networks including backbone or backhaul carriers in cellular networks linking BTS-BSC and BSC-MSC.
 * Radar
 * Radio astronomy
 * Communications intelligence
 * Electronic warfare

Reflector antennas
A parabolic antenna is an antenna that uses a parabolic reflector, a curved surface with the cross-sectional shape of a parabola, to direct the radio waves. These devices range anywhere from 6" to more than 12' diameter depending on application and use.

Horn antennas
A horn antenna or microwave horn is an antenna that consists of a flaring metal waveguide shaped like a horn to direct radio waves in a beam. Horns are widely used as antennas at UHF and microwave frequencies, above 300 MHz.

Lens antennas
A lens antenna uses a lens to direct or collect microwave radiation.

Array antennas
An array antenna is a high gain antenna consisting of an array of smaller antenna elements.

Leaky wave antenna
A leaky wave antenna uses a leaking transmission line to obtain radiation.

Spiral antenna
A spiral antenna, configured in the shape of a spiral, serves as a radio frequency antenna. It can function independently or as a feeder for satellite communication reflector antennas. It ensures excellent impedance matching and radiation pattern performance across the entire operating frequency band.
