Radio signals with a frequency greater than 100GHz, called the terahertz band, allow for increases in usable frequency range and communication speed of more than 100 times compared with the 0.8-2.0 GHz range used by current mobile devices. Now, Fujitsu has developed technology that combines a receiver-amplifier chip and terahertz-band antenna with a low-loss connection. This has made it possible to reduce the receiver's size to one tenth that of previous receivers, making use in mobile devices possible.
