This paper outlines the development of an electronically steerable receive-only array antenna realized within a project funded by the European Space Agency (ESA): the NATALIA project. The antenna has been designed for the reception of mobile satellite services in Ku-band and targets the European high-end automotive market. Based on an innovative polarization agile phased array concept, the antenna is highly compact in size, has a cost-effective buildup, and shows excellent RF-performance.
