Abstract: An antenna module for receiving a multiplicity of radiofrequency signals comprises a first patch antenna (2) with a second patch antenna (3) disposed above it. The first patch antenna (2) comprises a first dielectric substrate (4) having a top surface (5) with a first antenna structure (6) made of a first electrically conductive layer (7) laying thereon, and a bottom surface (8) with a second layer of electrically conductive material (9) thereon. The second patch antenna (3) comprises a second dielectric substrate (10) having a top surface (11) with a second antenna structure (12) made of a third electrically conductive layer (13) laying thereon, and a bottom surface (14) with a fourth layer of electrically conductive material (15) thereon. One of the first (6) and second antenna structures (12) has a substantially circular or elliptical surface, and the other has a substantially polygonal surface.
