Bande V (micro-ondes)

Pour les articles homonymes, voir Bande V.

La bande V est une bande de fréquences du spectre électromagnétique allant de 40 à 75 GHz selon la norme IEEE 521-1984^[1]^,^[2]. La longueur d'onde dans le vide est alors inférieure au centimètre et on parle d'ondes millimétriques.

Elle ne doit pas être confondue avec la Bande V (600–900 MHz) du domaine de fréquences UHF.

Utilisation

La bande V était assez peu utilisée jusqu'au années 2020, pour des faisceaux hertziens, par les satellites de télécommunications et des constellation de satellites (Starlink par exemple), pour certaines normes Wi-Fi à courte portée (IEEE 802.11ad et ay), par des radars millimétriques de recherche et d'autres types de recherches scientifiques.
