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 multi-band antenna includes a ground plane, a single antenna element, a frequency multiplexing circuit and at least two feeding strips coupled between the frequency multiplexing circuit and the single antenna element. Furthermore, the feeding of the antenna is arranged by one or more feeding points arranged between the ground plane and the frequency multiplexing circuit. According to first implementation one feeding point is arranged for at least two antenna branches. The signal fed into the feeding point is multiplexed by the multiplexing circuit to the antenna branches. According to at least one other implementation a dedicated feeding point is arranged for each of the antenna branches. At the same time the isolation of the frequencies between the different branches is arranged. This can be achieved e.g. by a multiplexing circuit. Moreover, impedance of the antenna branches can be matched with matching circuitry.

Abstract: 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.

Abstract: An electronic device includes a housing having a first side and a second side, a dielectric cover on the second side, and an electrically conductive peripheral structure along edges of the first and second sides. An antenna feed is coupled to a portion of the peripheral structure for using the portion as a radiating antenna element. A conductive member is located on or underneath the dielectric cover. A 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.
