The J band is the range of radio frequencies from 10 GHz to 20 GHz in the electromagnetic spectrum. This is equal to wave lengths between 3 cm and 1.5 cm. The J band is in the SHF range of the radio spectrum. The I band intersects with the X band and K band of the older classification system. The Ku band is within the J band.
Uses
The J band is used for satellite communications and radar.
