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...
This paper reviews recent results of wireless transmitter and receiver ICs at 122 and 245 GHz in 0.13 µm SiGe BiCMOS technology together with an efficient on-chip antenna. A transmitter IC with 5 dBm output power and directional onchip power measurement for built-in-self-test is presented. A 122 GHz passive HBT diode mixer design is discussed and results are shown. The mixer exhibits superior 1/f...
To fast calculate the radar cross section (RCS) of an arbitrarily shaped three-dimensional (3D) perfect electric conductor (PEC) body over a frequency band, the method of moments (MOM) in conjunction with the general asymptotic waveform evaluation (GAWE) is applied in this paper. And the 3D body is modelled by the non-uniform rational B-spline (NURBS) surface through the compute aided geometric design...
This paper concentrates on the bistatic SAR (BiSAR) signal processing for the spaceborne/airborne hybrid bistatic configuration. A bistatic SAR experiment based on this hybrid configuration is being planned in cooperation with FGAN/FHR and DLR. Due to the extreme differences of the platform's velocities and altitudes, the spaceborne system works in the sliding spotlight mode, while the airborne system...
