摘要:
Low cost millimeter wave imagers using two-dimensional focal plane arrays based on backward tunneling diode (BTD) detectors. Two-dimensional focal arrays of BTD detectors are used as focal plane arrays in imagers. High responsivity of BTD detectors near zero bias results in low noise detectors that alleviate the need for expensive and heat generating low noise amplifiers or Dicke switches in the imager. BTD detectors are installed on a printed circuit board using flip chip packaging technology and horn antennas direct the waves toward the flip chip including the BTD detectors. The assembly of the horn antennas, flip chips, printed circuit board substrate, and interconnects together work as an imaging sensor. Corrugated surfaces of the components prevent re-radiation of the incident waves.
摘要:
A point-to-point radio communications device, with an integrated antenna-IC module, includes highly-directional antenna elements and silicon CMOS-based ICs in plastic packaging material. The high-gain horn-type antenna includes two sections made of molded plastic and covered in a metallic coating. When combined, the two sections form an aperture and an opening on a face. The face of the antenna element can be mounted directly to an integrated circuit with an antenna coupling element, such that the aperture forms a horn-IC module. The module can be completely enclosed in a plastic-packaging environment using low-cost approach. The antenna-IC module can be manufactured as an integral part of a case for a point-to-point wireless electronic device such as a mobile video phone or a set-top box with tens of gigabits of video downloading capability.

摘要:
A multiband millimeterwave antenna system for communicating signals in multiple frequency bands is disclosed. A main antenna body is connected to antenna extensions by micro-electro-mechanical switches. By opening and closing the switches, the length of the antenna can be altered. The antenna is coupled to a microstrip feed line by an aperture. A series of matching stubs match the impedance of the feed line for the various signal frequencies.
摘要:
Methods for the design and fabrication of micro-electro-mechanical switches are disclosed. Two different switch designs with three different switch fabrication techniques are presented for a total of six switch structures. Each switch has a multiple-layer armature with a suspended biasing electrode and a conducting transmission line affixed to the structural layer of the armature. A conducting dimple is connected to the conducting line to provide a reliable region of contact for the switch. The switch is fabricated using silicon nitride as the armature structural layer and silicon dioxide as the sacrificial layer supporting the armature during fabrication. Hydrofluoric acid is used to remove the silicon dioxide layer with post-processing in a critical point dryer to increase yield.
摘要:
Disclosed are integration approaches for mm-wave planar phased array type architectures using multilayer substrate technologies. For instance, an apparatus may include a plurality of substrate layers, an integrated circuit, and a connector module. The plurality of substrate layers includes a first substrate layer having one or more phased array elements. The integrated circuit exchange one or more radio frequency (RF) signals (e.g., mm-wave signals) with the one or more phased array elements. The connector module exchange further signals with the integrated circuit that correspond to the one or more RF signals. For example, these further signals may be baseband or intermediate frequency (IF) signals.
