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.

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