  2. Microwave - Wikipedia

    en.wikipedia.org/wiki/Microwave

    k u band microstrip circuit used in satellite television dish. Prior to the 1970s microwave devices and circuits were bulky and expensive, so microwave frequencies were generally limited to the output stage of transmitters and the RF front end of receivers, and signals were heterodyned to a lower intermediate frequency for processing.

  3. Microwave transmission - Wikipedia

    en.wikipedia.org/wiki/Microwave_transmission

    Microwave radio transmission is commonly used in point-to-point communication systems on the surface of the Earth, in satellite communications, and in deep space radio communications. Other parts of the microwave radio band are used for radars, radio navigation systems, sensor systems, and radio astronomy.

  4. Ku band - Wikipedia

    en.wikipedia.org/wiki/Ku_band

    The K u band (/ ˌ k eɪ ˈ j uː /) is the portion of the electromagnetic spectrum in the microwave range of frequencies from 12 to 18 gigahertz (GHz). The symbol is short for "K-under" (originally German: Kurz-unten), because it is the lower part of the original NATO K band, which was split into three bands (K u, K, and K a) because of the presence of the atmospheric water vapor resonance ...

  5. Ka band - Wikipedia

    en.wikipedia.org/wiki/Ka_band

    The K a band (pronounced as either "kay-ay band" or "ka band") is a portion of the microwave part of the electromagnetic spectrum. The designation "K a-band" is from Kurz-above, which stems from the German word kurz, meaning "short". [1] There is no standard definition of Ka-band.

  6. Electromagnetic spectrum - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_spectrum

    A diagram of the electromagnetic spectrum, showing various properties across the range of frequencies and wavelengths. The electromagnetic spectrum is the full range of electromagnetic radiation, organized by frequency or wavelength.

  7. K band (IEEE) - Wikipedia

    en.wikipedia.org/wiki/K_band_(IEEE)

    The IEEE K-band is a portion of the radio spectrum in the microwave range of frequencies from 18 to 27 gigahertz (GHz). The range of frequencies in the center of the K-band between 18 and 26.5 GHz are absorbed by water vapor in the atmosphere due to its resonance peak at 22.24 GHz, 1.35 cm (0.53 in).

  9. V band - Wikipedia

    en.wikipedia.org/wiki/V_band

    The V band ("vee-band") is a standard designation by the Institute of Electrical and Electronics Engineers (IEEE) for a band of frequencies in the microwave portion of the electromagnetic spectrum ranging from 40 to 75 gigahertz (GHz). [1] [2] The V band is not heavily used, except for millimeter wave radar research and other kinds of ...
