High gain antenna for sub-millimeter wave communications

Nowadays the increase of high data rate communication applications requires high bandwidth at sub-millimeter wave frequencies and above, therefore high performance antennas are needed. This paper presents the design, fabrication and test of a high gain offset parabolic reflector antenna at sub-millimeter wave frequencies using typical machining techniques. The high gain antenna is focused on a 330 GHz communication link test with up to 70 GHz bandwidth with the goal to set up a 50 Gbit/s data rate link, over 100 m distance.
