A multiband patch antenna, a method for receiving radio frequency signals in multiple bands by a multiband patch antenna and a method of producing a patch element are disclosed. The antenna comprises a substrate layer having a first surface and a second surface and a base element on the first surface. A multi-resonance patch element comprising a pattern of outward extending resonance formations is provided on the second surface. At least two proximity feed elements configured for connection to a multiband hybrid coupler circuit and extending within the substrate layer from the first surface to the second surface are also provided. The multi-resonance patch element is configured to leave areas where the proximity feed elements extend to the second surface uncovered by the multi-resonance patch element.
