All warm objects radiate high frequency radio waves (microwaves) as part of their black body radiation.
Antenna (radio)
15 linksAntenna or aerial is the interface between radio waves propagating through space and electric currents moving in metal conductors, used with a transmitter or receiver.
Antenna or aerial is the interface between radio waves propagating through space and electric currents moving in metal conductors, used with a transmitter or receiver.
A receiving antenna may include not only the passive metal receiving elements, but also an integrated preamplifier or mixer, especially at and above microwave frequencies.
Radio receiver
15 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.
Satellite TV receiver - a set-top box which receives subscription direct-broadcast satellite television, and displays it on an ordinary television. A rooftop satellite dish receives many channels all modulated on a Ku band microwave downlink signal from a geostationary direct broadcast satellite 22,000 mi above the Earth, and the signal is converted to a lower intermediate frequency and transported to the box through a coaxial cable. The subscriber pays a monthly fee.
Electromagnetic radiation
10 linksIn physics, electromagnetic radiation (EMR) consists of waves of the electromagnetic (EM) field, propagating through space, carrying electromagnetic radiant energy.

It includes radio waves, microwaves, infrared, (visible) light, ultraviolet, X-rays, and gamma rays.
Communications satellite
11 linksArtificial satellite that relays and amplifies radio telecommunication signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth.

Satellite radio is a subscription radio service that broadcasts CD quality digital audio direct to subscribers' receivers using a microwave downlink signal from a direct broadcast communication satellite in geostationary orbit 22,000 miles above the Earth. It is mostly intended for car radios in vehicles. Satellite radio uses the 2.3 GHz S band in North America, in other parts of the world, it uses the 1.4 GHz L band allocated for DAB.
Microwave oven
10 linksA microwave oven (commonly referred to as a microwave) is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range.

Cavity magnetron
10 linksHigh-power vacuum tube used in early radar systems and currently in microwave ovens and linear particle accelerators.
High-power vacuum tube used in early radar systems and currently in microwave ovens and linear particle accelerators.
It generates microwaves using the interaction of a stream of electrons with a magnetic field while moving past a series of cavity resonators, which are small, open cavities in a metal block.
Radar
13 linksDetection system that uses radio waves to determine the distance (ranging), angle, and radial velocity of objects relative to the site.
Detection system that uses radio waves to determine the distance (ranging), angle, and radial velocity of objects relative to the site.
A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects.
