“…1, will be 36 dBi. For traditional car radar applications, the beam steering has been achieved using a dielectric lens or a Rotman lens [14]- [17]. Instead, in the radar system 0018-9200/$20.00 © 2006 IEEE for which the amplifier in this work is designed, a phased-array transceiver with beam steering in both transmit and receive (TX and RX) paths is employed [7], [8].…”

“…The 18-dB required directivity at each path can be achieved with 16 elements providing 12 dB of array directivity combined with a typical directivity of a patch or dipole antenna ( 5 dB). Since there is no need to scan in the elevation plane, the required directivity in the elevation can be realized by narrowing the antenna beam in the elevation plane (e.g., using serially fed patches [17]- [19]). In this case, just four elements for beam steering in the azimuthal plane will be enough.…”

Abstract-A 77-GHz, +17.5 dBm power amplifier (PA) with fully integrated 50-input and output matching and fabricated in a 0.12-m SiGe BiCMOS process is presented. The PA achieves a peak power gain of 17 dB and a maximum single-ended output power of 17.5 dBm with 12.8% of power-added efficiency (PAE). It has a 3-dB bandwidth of 15 GHz and draws 165 mA from a 1.8-V supply. Conductor-backed coplanar waveguide (CBCPW) is used as the transmission line structure resulting in large isolation between adjacent lines, enabling integration of the PA in an area of 0.6 mm 2 . By using a separate image-rejection filter incorporated before the PA, the rejection at IF frequency of 25 GHz is improved by 35 dB, helping to keep the PA design wideband.

“…The operation frequency is typically in the 76-77 GHz band for frequency-modulated continuous wave (FMCW) or pulse Doppler operation. The higher bandwidth allows for W-band ultra-wideband (UWB) systems with improved distance resolution, which were previously the main target of 24 GHz automotive radar development [8].…”

Abstract-This paper proposes a 77 GHz microstrip series-fed patch antenna array for automotive radar applications. Based on the Taylor Distribution Principle, we designed a six-unit series-fed weighted antenna array. A Wilkinson 1 : 8 un-equal divider is employed to connect eight antenna arrays to form a whole planar antenna. In antenna far-field patterns, the E-plane side-lobe level is approximately below −20.15 dB, and the H-plane side-lobe level is about −15 dB. Good accordance is obtained between simulated and measured results. The designed antenna has great value in the application fields of 77 GHz automotive radar antenna.

Abstract-A 3-bit phase array system including phase shifter blocks and antenna elements has been developed on a coplanar waveguide (CPW) using micro electromechanical system (MEMS) technology. The non Euclidean Koch fractal geometry has been used to improve the frequency behavior of the entire system. It is shown that the fractal geometry makes the design to have lower profile, wider frequency bandwidth, and lower mutual coupling effects. It also decreases the actuation voltage of the MEMS switch elements. The fabrication process has been fully described and the measured values regarding every single block is presented.
