A microwave antenna is a physical transmission device used to broadcast microwave transmissions between two or more locations.^[1] In addition to broadcasting, antennas are also used in radar, radio astronomy and electronic warfare.

• 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

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.^[3]

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.
