Микротолқынды антенна түрлері және олардың жиіліктері

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.

+ Radio bands where microwave antennas are commonly deployed in 2016 FCC C band 4 to 8 GHz 3.75 cm to 7.5 cm 4 GHz, 6 GHz X band 8 to 12 GHz 25 mm to 37.5 mm 10 GHz, 11 GHz Ku band 12 to 18 GHz 16.7 mm to 25 mm 12 GHz, 18 GHz K band 18 to 26.5 GHz 11.3 mm to 16.7 mm 18 GHz Ka band 26.5 to 40 GHz 5.0 mm to 11.3 mm 23 GHz, 31 GHz Q band 33 to 50 GHz 6.0 mm to 9.0 mm 38 GHz W band 75 to 110 GHz 2.7 mm to 4.0 mm 70 GHz, 80 GHz, 90 GHz

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.

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.

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

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

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

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.
