Dipole antenna
19 linksIn radio and telecommunications a dipole antenna or doublet is the simplest and most widely used class of antenna.
Microwave
15 linksForm of electromagnetic radiation with wavelengths ranging from about one meter to one millimeter corresponding to frequencies between 300 MHz and 300 GHz respectively.
Form of electromagnetic radiation with wavelengths ranging from about one meter to one millimeter corresponding to frequencies between 300 MHz and 300 GHz respectively.
Their short wavelength also allows narrow beams of microwaves to be produced by conveniently small high gain antennas from a half meter to 5 meters in diameter.
Radio

Technology of signaling and communicating using radio waves.
They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves, and received by another antenna connected to a radio receiver.
Radio receiver
11 linksElectronic device that receives radio waves and converts the information carried by them to a usable form.
Electronic device that receives radio waves and converts the information carried by them to a usable form.
It is used with an antenna.
Radio wave
11 linksRadio waves are a type of electromagnetic radiation with the longest wavelengths in the electromagnetic spectrum, typically with frequencies of 300 gigahertz (GHz) and below.
Radio waves are a type of electromagnetic radiation with the longest wavelengths in the electromagnetic spectrum, typically with frequencies of 300 gigahertz (GHz) and below.
Radio waves are generated artificially by an electronic device called a transmitter, which is connected to an antenna which radiates the waves.
Parabolic antenna
10 linksA 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 to the receiver in its focal point.
Monopole antenna
11 linksA monopole antenna is a class of radio antenna consisting of a straight rod-shaped conductor, often mounted perpendicularly over some type of conductive surface, called a ground plane.
Transmitter
8 linksIn electronics and telecommunications, a radio transmitter or just transmitter is an electronic device which produces radio waves with an antenna.
Radiation pattern
8 linksIn the field of antenna design the term radiation pattern (or antenna pattern or far-field pattern) refers to the directional (angular) dependence of the strength of the radio waves from the antenna or other source.
Yagi–Uda antenna
7 linksA Yagi–Uda antenna or simply Yagi antenna, is a directional antenna consisting of two or more parallel resonant antenna elements in an end-fire array; these elements are most often metal rods acting as half-wave dipoles.
