Viktiga resultat som projektet gav
A micromachine technique that could be useful to fabricate D-band antenna in a low cost and time efficient way has been demonstrated during the project. Three different micromachine techniques namely SU-8 microfabrication, PDMS molding and injection molding of OSTEMER have been utilized. The demonstrated fabrication method partially needs cleanroom facilities. The final antenna parts can be fabricated outside the cleanroom facilities. The fabricated antenna has good agreement with the simulation result and measured antenna performance is suitable for LOS-MIMO application.
Långsiktiga effekter som förväntas
The main findings from the MIMO studies are: · The designed antenna should work excellently for a LOS MIMO system. The directivity of the antennas will not limit the achievable capacity from spatial multiplexing. · A M*M MIMO system can have a better link budget than M independent SISO systems, due to that each TX antenna can be picked up by many RX antennas. · The antenna distance is very important to get optimal performance. The 140 GHz LOS MIMO link has a better form factor (it is smaller) than lower frequencies.
