Abstract
The aim of this work is to design a smart and cost effective 24 GHz Short Range Radar (SRR) array antenna system for automotive applications. The beam forming network consists of a hybrid solution including an analog phase shifter, realized with a Rotman lens, and an additional digital phase shifting stage on array side allowing to select between two states, and consequently to enhance the scan angle. This paper will demonstrate that this new concept allows to double the scanning capability of the array with respect to a design employing only the Rotman lens.
