Abstract

A dual-polarization antenna array (1) comprising a conductive structure (2) having an aperture pattern comprising at least one first aperture (3) having a first configuration and at least one second aperture (4) having a second configuration. The first aperture (3) is directly interconnected with at least one second aperture (4). At least one first coupling element (5) is connected to a first antenna feed line (6), and at least one second coupling element (7) is connected to a second antenna feed line (8). The first coupling element (5) is configured to excite an electrical field having a first polarization, and the second coupling element (7) is configured to excite an electrical field having a second polarization. Each first coupling element (5) is at least partially juxtaposed with one first aperture (3), allowing the electrical field having a first polarization to be transmitted and/or received through the first aperture (3). Each second coupling element (7) is at least partially juxtaposed with one second aperture (4), allowing the electrical field having a second polarization to be transmitted and/or received through the second aperture (4). A dual-polarized antenna array (1) arranged within the same space of a conductive structure reduces the volume needed for providing an efficient antenna array having omnicoverage, or near omnicoverage.
