Abstract :
Endfire slotline antennas have been integrated on a 1.75 mu m-thick dielectric substrate. The thin substrate allows the upper frequency limit of the slotline antennas to be pushed beyond 1 THz. Antennas have been fabricated and tested at 350 and 802 GHz. The patterns exhibit high directivity (15+or-1 dB) and wide bandwidth. In the future, these antennas will be combined with SIS junctions for low-noise astronomical receivers.<>
