“…A new quasi-optic design is then proposed for low-cost, easy-manufactured and reproducible high space-sampled multi-pixel arrays (figure 1). This design, which is proposed in [5] presents excellent gain parameters.…”

“…This technology will ideally increase the mapping speed, allow fine details and large fields of view. Already some array developments have been made, with direct detectors [1,2], diodes [3,4], SIS [5] or heterodyne HEB [6], which are demonstrated to be the best components for THz observations [7][8][9][10] Silicon lenses or feed-horns are usually used [11,12], which present some inconvenience concerning the coupling efficiency or the Focal plane sampling. Some others have used planar antennas [13,14].…”

We present in this paper the front-end design and the results of RF simulations, carried out with Microwave Studio (CST) and HFSS for SHAHIRA (Submillimeter Heterodyne Array for High-speed Radio Astronomy), a 4×4 heterodyne array at 2.5 THz and 4.7 THz. One can then observe 16 spatial positions at 2 frequencies. The design has been chosen to be quasi-optic, because of its simplicity, novelty and multi-pixels applicability. Pixels are made of Niobium Nitride HEB mixers with double-slot antennas, processed on 1 µm thick stress-less Si 3 N 4 /SiO 2 membrane. The use of the membrane shows numerous advantages: for instance the use of the mixers at higher RF frequencies, a better power coupling efficiency or a solution for avoiding dielectric modes, losses and reflections. This work is supported by ESA and is a collaboration between LERMA, CHALMERS and LAAS. The Camera is expected to find applications, for SOFIA or CIDRE.

“…Filipovic et al have pointed out that a single lens can be used for an array of tens of antennas, which would simplify the manufacturing of the lens array [13]. An alternative to using a dielectric lens is to manufacture the antennas on silicon-nitride membranes and use a parabolic reflector behind each antenna as described by Filipovic et al [14] If the telescope is matched to the f/# ~ 1 of the membrane-mounted double-slot dipole a simple flat reflector can be used.…”

Abstract. We report on the development of antenna-coupled Voltage-biased Superconducting Bolometers (VSBs) which use Transition-edge Sensors (TES). Antenna coupling can greatly simplify the fabrication of large multi-frequency bolometer arrays compared to horn-coupled techniques. This simplification can make it practical to implement 1000+ element arrays that fill the focal plane of mm/sub-mm wave telescopes. We have designed a prototype device with a double-slot dipole antenna, integrated band-defining filters, and a membrane-suspended bolometer. A test chip has been constructed and will be tested shortly.

“…With increasing frequency the fields and surface currents concentrate around the slots, and finally the quasi-TE slot-line mode occurs. The coplanar stripline is due to its balanced nature, ideally suited as a feed line for printed dipole antennas [67]. Passive elements for coplanar MMIC's are reported in [34].…”

Monolithic integrated millimeter-wave circuits based on silicon and SiGe are emerging as an attractive option in the field of millimeter-wave communications and millimeterwave sensorics. The combination of active devices with passive planar structures, including also antenna elements, allows single-chip realizations of complete millimeter-wave front-ends. This paper reviews the state-of-the-art silicon-and SiGe-based monolithic integrated millimeter-wave circuits. The technological background as well as active and nonlinear devices and passive circuit structures suitable for silicon-and SiGe-based monolithic integrated millimeter-wave circuits are discussed. Examples of such integrated circuits and first systems applications are also presented.Index Terms-Millimeter-wave IC, silicon-based RF circuits.
