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.

摘要： An example dual-polarization antenna element comprises a radiator layer and a resonator layer. The radiator layer comprises a planar antenna radiator, the planar antenna radiator comprising a split ring, enclosing a dielectric area and having ends separated by a first dielectric gap, and two second radiator sections extending from said ends. The resonator layer comprises a center resonator superimposed with said dielectric area and two offset resonator arrangements. Each offset resonator arrangement is at least partially superimposed with one of said second radiator sections, and each offset resonator arrangement comprises at least one sub-resonator. A feed arrangement is at least partially arranged in said radiator layer or in an additional feed layer.

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： An antenna arrangement is described. The antenna arrangement comprises an antenna array that includes a first antenna element having a first feed point, and a second antenna element having a second feed point. The antenna arrangement further comprises a signal processing device configured to receive an input signal (Sin), obtain a first complex weight (w1), obtain a second complex weight (w2), generate a first feed signal (a1) based on the input signal (Sin) and the first complex weight (w1), generate a second feed signal (a2) based on the input signal (Sin) and the second complex weight (w2), provide the first feed signal (a1) to the first feed point, and provide the second feed signal (a2) to the second feed point so as to control the frequency characteristic of the antenna array. A method for such an antenna arrangement is also described.

摘要： An electronic device comprises a housing having a first side and a second side, a dielectric cover (602) on said second side, and an electrically conductive peripheral structure along edges of said first and second sides. An antenna feed (601) is coupled to a portion (603) of said peripheral structure for using said portion (603) as a radiating antenna element. A conductive member (604, 804) is located on or underneath said dielectric cover (602). The purpose of the conductive member is to enlarge the surface area where the electric field is distributed on to increase the antenna aperture for radiation.

摘要： An example radiation field beam steering arrangement includes a substrate having a reflector surface, a conductive element extending at least partially adjacent a periphery of the substrate, and at least one end-fire antenna element superimposed with the substrate and comprising an antenna radiator. The reflector surface comprises a plurality of reflectors, each reflector having a hollow profile and is configured to reflect at least a part of a radiation field generated by the antenna radiator that is towards a main beam direction oriented parallel to a main plane of the substrate.

摘要： A redirecting structure for electromagnetic waves, the redirecting structure comprising a first reflection passage formed between a first conductive element and a second conductive element, and an antenna structure comprising an antenna element and a radiation passage extending from the antenna element in a first direction. The antenna structure is connected to the first reflection passage at a first interface, the first reflection passage extending in a second direction different from the first direction. A first reflective structure is associated with an interior of the first reflection passage and is arranged at a predetermined distance from the first interface such that electromagnetic waves propagating from the antenna structure into the first reflection passage are reflected to the radiation passage by the first reflective structure.
