In a transmitting antenna, it feeds the radio frequency (RF) current from the transmitter to the antenna, where the energy in the current is radiated as radio waves. In a receiving antenna it transfers the tiny RF voltage induced in the antenna by the radio wave to the receiver.

Spacetime Engineering was established in 2013 to provide state-of-the-art RF components and antenna feeds to the satellite communication industry. We offer a rapidly growing line of standard products, ready to ship and quantity pricing.

Vitesse systems consistently delivers high-performance single and multi-band feed assemblies that are competitive on mass, form factor, and price.

AEM Antennas supplies feed networks and direct radiating horns in various network configurations. Using the newest Industry 4.0 manufacturing techniques including 3d printing, single-part monolithic feeds can be produced to facilitate assembly complexity and reduce significant weight.

Otherwise known as transmission lines, feedlines are used to transfer RF energy between a Transmitter, Receiver or transceiver and the antenna. Three types of feed lines are used by amateurs: Coax, Balanced Line, and Waveguide.

Orbital Systems provides a wide range of antenna feeds for Earth Observation Satellites (EOS) Direct Broadcast (DB), Telemetry, Tracking and Control (TT&C), and general telemetry applications.

Active phased array antennas are antennas at which the transmit power is produced by many rx/tx- modules of low impact on the antenna directly. E.g.: the airborne Tornado-Nose-Radar, the air defense radar AN/FPS-117 and the naval radar APAR .
