Abstract: 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.

Abstract: 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.

Abstract: The disclosure relates to suppressing surface waves in a communication device for a wireless communication system. The communication device includes a dielectric layer extending along a plane between a chassis and a glass layer, an antenna element configured to emit a radio wave, and a retroreflective structure extending inside the dielectric layer and being located adjacent to the antenna element, and where the retroreflective structure is configured to reflect the radio wave in an angle non-parallel to the plane. The retroreflective structure hence prevents parasitic channeling of the antenna energy into surface waves in and behind the glass layer and directs the radiation into the desired direction.

Abstract: An antenna arrangement for a communication device comprises a top conductive patch comprising at least a first coupling point and a second coupling point coupled to one or more feed circuits carrying a radio frequency (RF) signal to or from the top conductive patch. The RF signal has a first phase in the first coupling point and a second phase in the second coupling point. A first slot extends in the conductive patch between the first coupling point and the second coupling point. The antenna arrangement according enables a desired current distribution to be realized in the antenna in a controlled and systematic manner. A communication device includes such an antenna arrangement.

Abstract: A beam steering antenna structure comprising a printed circuit board and a conductive component, a first wall and a second wall of the printed circuit board being juxtaposed with a first surface of the conductive component, the second wall abutting and being galvanically connected to the first surface. A second surface of the conductive component extends at an angle from the first surface. A connecting surface extends between the first wall and the second wall such that a groove is formed, the groove being partially juxtaposed to the first surface. The groove comprises a first antenna array and a second antenna array transmitting or receiving, respectively, a first radiation beam and a second radiation beam having orthogonal polarizations. The second surface steers at least one of the first or second radiation beam in a direction away from or towards the connecting surface.
