   Abstract : The millimeter wave frequency range has got a lot of attention over the past few years because it contains unused frequency spectrum resources that are suitable for delivering Gbit/s end-user access in areas with high user density. Due to the limited output power that current RF active components can deliver in millimeter waves, antennas with the merits of low profile, high gain, high effciency and low cost are needed to compensate free space path loss and increase the communication distance for the emerging high data rate wireless systems.

6. 4. Advanced Dual Circularly Polarized Antenna for Automotive Radar Systems

   Author : Zhaorui Zang; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; radar; Antenna; polarimetric radar.; automotive; gap waveguide; dual circular polarization; low-profile;

   Abstract : Advanced driver assistance systems (ADAS) promise reliable support for collision avoidance and cruise control. The demand for precise target classification and road surface sensing requires a sensor revolution. In this regard, the automotive radar system is highly expected to collect as much information as possible. READ MORE
