Abstract
An apparatus embedded with one or more terahertz transceivers is described. The one or more terahertz transceivers based on at least one resonant tunnelling diodes is provided to facilitate wireless communication in the apparatus, where the apparatus is embedded with one or more planar antennas. The transceiver operates in terahertz and may be coupled to one or two different antennas, one for transmission and the other for reception.
Claims14
An apparatus communicating wirelessly with a remote device, the apparatus comprising:
- an antenna set;
- one or more terahertz transceivers coupled to the antenna set to exchange signals with the remote device in one or more predefined frequency bands, wherein each of the terahertz transceivers comprises:
- at least one resonant tunnelling diode in double-barrier quantum well structure with predefined dimensions, some or all of the dimensions are adjusted in accordance with a predefined resonant frequency;
- a slot antenna, coupled to the resonant tunnelling diode, forming a standing wave of electromagnetic field as a resonator to output a resonant signal in the predefined resonant frequency;
- a band filter to process the resonant signal and output a terahertz (THz) signal after amplified;
- a local oscillator receiving the THz signal and producing a reference signal;
- and
- an I/O mixer provided to modulate the reference signal with a signal.
