  text: Two half-wavelength 122 GHz patch antennas were designed and manufactured
    by using Benzocyclobutene (BCB) as a dielectric layer above the SiGe BiCMOS wafer.
    It enables the full integration of the millimeter-wave transceiver circuits and
    the antennas on a single chip to simplify the packaging procedure at millimeter-wave
    frequencies, thereby reducing the cost. The two patch antennas are fed by different
    feeding methods, i.e. microstrip transmission line direct feed and proximity-coupled
    feed. They exhibit similar performance and offer the flexibility of designing
    the interconnects (feed lines routing) between the circuits and the antennas within
    the very limited chip area. The measured gain is 3.4 dBi at 122.5 GHz (the center
    frequency of the ISM band of 122-123 GHz) for both designs with a simulated efficiency
    of about 50%.

  text: In this paper, an integrated dielectric sensor with a read-out circuit in
    an unmodified SiGe BiCMOS technology at 125 GHz is presented. The sensor consists
    of a 500-μm shorted half-wave coplanar-waveguide transmission line in the uppermost
    metal layer of the silicon process, while the read-out is obtained by reflection
    coefficient measurement with an integrated reflectometer and a signal source.
    The reflectometer is verified with a circuit breakout including an integrated
    dummy sensor. The reflectometer is able to measure the phase of the reflection
    coefficient from 117 to 134 GHz with a resolution of 0.1° and a standard deviation
    of 0.082°. The integrated sensor with the reflectometer circuit have been fabricated
    in a 190-GHz fT SiGe:C BiCMOS technology. It spans an area of 1.4 mm 2 and consumes
    75 mA from a 3.3-V supply. The circuit has been assembled on a printed circuit
    board for characterization by immersion into test liquids. The sensor is controlled
    by a controller board and a personal computer enabling a measurement time of up
    to 1 ms per frequency point. Functionality of the sensor is demonstrated from
    118 to 133 GHz with immersion of the sensor into different binary methanol-ethanol
    mixtures, showing good correlation between theory and measurement. The sensor
    shows a standard deviation of the measured phase of 0.220° and is able to detect
    a difference in ε' r of 0.0125

  text: This paper describes the design of D-band phased-array circuits in 0.25 μm
    technology. The first part describes the design of the passive components which
    are used in the phased-array systems such as balun, Wilkinson divider and branch-line
    coupler. A millimeter-wave vector-modulator is designed to support both amplitude
    and phase control for beam-forming applications. In the second part the designed
    circuits are integrated together to form a two channel 110-130 GHz phased-array
    chip. Each channel exhibits 360° phase control with 15 dB of amplitude control
    range and gain of -10 dB. The entire chip draws 45 mA from 3.3 V supply. The millimeter-wave
    phase shifting and the low-power consumption makes it ideal for highly integrated
    scalable beam-forming systems for both imaging and communication.

  text: This paper presents the packaging technology and the integrated antenna design
    for a miniaturized 122-GHz radar sensor. The package layout and the assembly process
    are shortly explained. Measurements of the antenna including the flip chip interconnect
    are presented that have been achieved by replacing the IC with a dummy chip that
    only contains a through-line. Afterwards, radiation pattern measurements are shown
    that were recorded using the radar sensor as transmitter. Finally, details of
    the fully integrated radar sensor are given, together with results of the first
    Doppler measurements.

  text: In this paper we propose an approach to retrieve the absolute geometry of
    an acoustic sensor network, consisting of spatially distributed microphone arrays,
    from reverberant speech input. The calibration relies on direction of arrival
    measurements of the individual arrays. The proposed calibration algorithm is derived
    from a maximum-likelihood approach employing circular statistics. Since a sensor
    node consists of a microphone array with known intra-array geometry, we are able
    to obtain an absolute geometry estimate, including angles and distances. Simulation
    results demonstrate the effectiveness of the approach.
