Transport networks, network elements, and methods of use are described herein, including a transmitter comprising a client-side input, transmitter circuitry, and antennas. The client-side input is configured to receive baseband signals having client data encoded therein. The transmitter circuitry is configured to receive the baseband signals from the client-side input and generate antenna feed signals based on the baseband signals. The antennas are configured to receive the antenna feed signals from the transmitter circuitry, generate radiated signals based on the antenna feed signals, and couple the radiated signals into a hollow waveguide. Each of the radiated signals is a radiated electromagnetic wave configured for coherent detection and has a frequency in a range between 300 Gigahertz (GHz) and 10 Terahertz (THz).

Fiber-coupled Terahertz transceiver system

A microwave helix antenna with a coaxial interface having controlled transmission properties is disclosed. In one aspect, dielectric beads surround a center conductor and are varied in number, thickness and spacing to achieve desired transmission properties.

Helix antenna feed structure with coaxial impedance control

A compact millimeter-wave surface mount helix antenna for high-speed data transport over low-cost plastic fiber is described. Guided millimeter-wave technology enables gigabit transport in the centimeter to meters range, complementing current transport technologies based on optical fibers, coaxial flyover assemblies, and PCB traces. To maintain signal integrity requires an efficient launch of millimeter-waves into the plastic fiber, with low loss and minimum signal impairment. A compact helix antenna provides efficient coupling and wide bandwidth, enabling meter-range copper-grade gigabit transport.
