Beam steering is a common technique within radar applications to scan for objects within a small dihedral angle. A flexible approach to achieve this uses variable phase shifters in front of each single antenna in an array. This paper presents delay line phase shifters for two common radar frequencies in the K and W-band of 24 and 77 GHz. The active components are capacitive RF MEMS switches. These...
In this paper we will present our latest research results of integrated silicon antennas for automotive radar applications (f = 80 GHz). The design procedure as well as simulation and first measurement results will be given. Within this work two antenna designs, a 1-dimensional array (single line antenna) and a 2-dimensional antenna array (4 lines with 4 patches), will be shown. First measurement...
