Abstract

This paper presents the conceptual design of a compact 2×2 array receiver for GNSS applications. Besides mere miniaturization, the goal of this work is also investigation on novel techniques for coping with the strong mutual coupling imposed in electrically small antenna arrays and RF front ends, by means of eigenmode reception and digital beamforming in the beam space.
