Embodiments of the present invention provide a dual-polarization antenna array that includes: a conductive structure having an aperture pattern including at least one first aperture and at least one second aperture, the first aperture(s) being directly interconnected with at least one second aperture. At least one first coupling element is connected to a first antenna feed line to excite a first electrical field having a first polarization. At least one second coupling element is connected to a second antenna feed line to excite a second electrical field having a second polarization. Each first coupling element is at least partially juxtaposed with one first aperture, allowing said first electrical field to be transmitted and/or received through said first aperture. Each second coupling element being at least partially juxtaposed with one second aperture, allowing said second electrical field to be transmitted and/or received through said second aperture.
