Despite the advantages of coplanar waveguide technology for high performance and low cost MMIC applications, its possibilities are still not thoroughly exploited for commercial applications. This paper presents an overview of trends and latest achievements in millimeter-wave coplanar integrated circuit design, such as modeling aspects, mounting techniques, and system applications. Coplanar circuit technology has shown its potential to be competitive with microstrip by recent solutions of the previously hindering technical and technological problems, and the realization of circuits for high performance millimeter-wave applications.

“…Frequencymodulated continuous-wave (FMCW) radar systems have successfully been applied to measure the distance and speed of moving targets for a very long time. In recent years, FMCW radar sensor systems have been employed in a variety of applications: 1) car radar systems, such as short-range radar [2] and long-range radar sensor for intelligent cruise control and collision avoidance; parking; anticollision warning; traffic monitoring; and stop-and-go [3]- [6] in addition to 2) airborne applications, such as commercial and military radar sensor systems with high-resolution sensing and compact system size [7]- [11]. By using a mixer in an FMCW RF module, the received FMCW chirp waveforms can be transformed into sinusoidal waveforms that convey range and angle information.…”

A low complexity range-azimuth frequencymodulated continuous-waveform (FMCW) radar sensor using joint angle and delay estimation method without singular value decomposition (SVD) and eigenvalue decomposition (EVD) is presented in this paper. Conventional joint angle and delay estimation techniques exploit the dual-shift-invariant structure of received signals through matrix decompositions, such as SVD and EVD, which increases the computational burden. The proposed method utilizes the dual-shift-invariant structure through matrix inversion and performs angle and delay estimation using extended one-dimensional pseudospectrum searching instead of two-dimensional pseudospectrum searching to reduce the computational complexity. We demonstrate the effectiveness of the proposed method through Monte-Carlo simulations. The proposed algorithm is also verified by processing real FMCW data collected in an anechoic chamber.

“…Figure 1 II. GaAs mHEMT DEVICE CHARACTERISTICS The high electron mobility transistors (HEMTs), especially InP-based InAlAs/InGaAs HEMTs with high cut off frequency and an excellent noise characteristic, are widely used in the front end of satellite communications, radio astronomy, and satellite direct broadcasting receiver systems at microwave and millimeter frequencies [4], [5]. However, it is difficult to use an InP substrate with a diameter of 4 inches or larger, because an InP-based HEMT wafer is more expensive and fragile than a GaAs-based HEMT wafer.…”

A monolithic microwave integrated circuit (MMIC) one-chip set consisting of a transmitter and a 8-stage low noise amplifier has been developed for automotive radar sensors at 77 GHz. The chip set was fabricated using a 0.15 gm gate-length InGaAs/InAlAs/GaAs metamorphic high electron mobility transistor (mHEMT) process based on a 4-inch substrate. The transmitter achieved an output power of 11 dBm at 76.5 GHz with a conversion gain of 6 dB for an input power of 5 dBm and a 38.25 GHz input frequency. The chip size is 5.1 mm x 2.2 mm. The 8-stage low noise amplifier exhibited a gain of 35 dB over a 76 to 77 GHz band with a noise figure of 6 dB. The chip size is 4.1 mm x 2.2 mm. This MMIC one-chip set is suitable for the 77 GHz automotive radar sensors and related applications in a W-band.
