2. Microwave transmission - Wikipedia

   en.wikipedia.org/wiki/Microwave_transmission

   A microwave link is a communications system that uses a beam of radio waves in the microwave frequency range to transmit video, audio, or data between two locations, which can be from just a few feet or meters to several miles or kilometers apart.

3. Dielectric resonator antenna - Wikipedia

   en.wikipedia.org/wiki/Dielectric_Resonator_Antenna

   DRAs offer simple coupling schemes to nearly all transmission lines used at microwave and mm-wave frequencies. This makes them suitable for integration into different planar technologies. The coupling between a DRA and the planar transmission line can be easily controlled by varying the position of the DRA with respect to the line.

4. Microwave - Wikipedia

   en.wikipedia.org/wiki/Microwave

   High-power microwave sources use specialized vacuum tubes to generate microwaves. These devices operate on different principles from low-frequency vacuum tubes, using the ballistic motion of electrons in a vacuum under the influence of controlling electric or magnetic fields, and include the magnetron (used in microwave ovens ), klystron ...

5. Microwave oven - Wikipedia

   en.wikipedia.org/wiki/Microwave_oven

   A microwave oven or simply microwave is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range. [1] This induces polar molecules in the food to rotate and produce thermal energy (heat) in a process known as dielectric heating .

6. Horn antenna - Wikipedia

   en.wikipedia.org/wiki/Horn_antenna

   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. [ 1 ]

8. Low-noise block downconverter - Wikipedia

   en.wikipedia.org/wiki/Low-noise_block_downconverter

   The microwave signal from the dish is picked up by a feedhorn on the LNB and is fed to a section of waveguide. One or more metal pins, or probes, protrude into the waveguide at right angles to the axis and act as antennas , feeding the signal to a printed circuit board inside the LNB's shielded box for processing.

9. Wilkinson power divider - Wikipedia

   en.wikipedia.org/wiki/Wilkinson_power_divider

   Power divider in microstrip technology. In the field of microwave engineering and circuit design, the Wilkinson Power Divider is a specific class of power divider circuit that can achieve isolation between the output ports while maintaining a matched condition on all ports.
