This paper presents experimental results exploring the performance of GNSS receivers equipped with controlled radiation pattern antennas. Experiments focus on identifying those features and characteristics of their implementation that may limit the achievable performance of signal-rejection techniques. The study describes both conductive and broadcast experiments conducted in a large anechoic chamber and computer-based Monte-Carlo simulations. Results include a precise gain pattern measurement of a typical antenna array, an investigation and comparison of both analogue RF and digital IF null steering along with some novel theoretical results.JRC.G.5-Security technology assessmen
