Abstract
We investigate adaptive antennas for ultra wideband (UWB) systems [1] working at around 310GHz to enhance the efficiency of frequency use and avoid serious fading caused by complicated interference in indoor environment. Because the fading happens at points where the electromagnetic-wave cancels out almost completely, the problem is often solved by changing the radiation direction roughly with a modest directivity with, e.g., a forward-back (F/B) ratio of several dB [2].
