摘要： 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.

摘要： A transmission line for transmitting radiofrequency range current between a first conductive element and a second conductive element, the transmission line comprising a signal current line and at least one return current line, the signal current line and the return current line(s) extending in parallel. Each current line comprises at least one first segment and at least one second segment. Each first segment is partially aligned with at least one adjacent second segment, aligned segments being separated by a first dielectric gap, and each aligned first segment and second segment forming a capacitive coupling across the first dielectric gap. This solution enables a transmission line which provides only small capacitive loading onto its surroundings, and which therefore can extend, e.g., through an antenna element without significantly affecting the performance of the antenna element.
