Antenna for wideband terahertz (thz) link

A transmitter, comprising:

• a client-side input configured to receive one or more baseband signals having client data encoded therein;
• transmitter circuitry configured to receive the one or more baseband signals from the client-side input and generate one or more antenna feed signals based on the one or more baseband signals;
• and
• one or more antennas configured to receive the one or more antenna feed signals from the transmitter circuitry, generate one or more radiated signals based on the one or more antenna feed signals, and couple the one or more radiated signals into one or more hollow waveguides, the one or more radiated signals being radiated electromagnetic waves configured for coherent detection and having one or more frequencies in a range between 300 Gigahertz (GHz) and 10 Terahertz (THz);
• wherein the one or more antennas include a waveguide probe antenna.
