Basic Antenna Terms and Definitions

From A.H. Systems Inc.

Antenna: An antenna is a device that transmits and/or receives electromagnetic waves. Electromagnetic waves are often referred to as radio waves. Most antennas are resonant devices, which operate efficiently over a relatively narrow frequency band. An antenna must be tuned to the same frequency band that the radio system to which it is connected operates in, otherwise reception and/or transmission will be impaired.

RF Waveguide Components
RF waveguide components are circular, elliptical or rectangular metal tubes or pipes through which electromagnetic waves are propagated in microwave and RF communications. The wave passing through the medium is forced to follow the path determined by the physical structure of the guide.
Horn Antennas
Horn antennas are used for the transmission and reception of microwave signals. They are usually fed by waveguides.
RF Amplifiers
RF amplifiers are devices that accept a varying input signal and produce an output signal that varies in the same way, but with larger amplitude.
Antennas
Antennas are structures or devices used to collect or radiate electromagnetic waves.
