Abstract: Systems and methods of a node in a wireless communication system with switchable antenna functions are provided. In one exemplary embodiment, a method by a controller for configuring a switching network may include configuring the switching network for a first mode of operation associated with multiple-input, multiple-output (MIMO) communications. Further, the method may include configuring the switching network for a second mode of operation associated with beamforming communications.

Abstract: The present invention relates to a method for alignment of a first node with at least one secondary node in a wireless communication network. The first node includes first node antenna beams with corresponding designated pointing angles. For each such beam, the method comprises the steps of, for each secondary node: directing a first node antenna beam in its designated pointing angle; using a secondary node antenna beam where objects can generate signal reflections/diffractions; and detecting at least one signal property of reflected/diffracted signals. The method further comprises the steps: exchanging information between the nodes, regarding beam angles resulting in said signal property exceeding a corresponding threshold level; and selecting a first node beam angle and a secondary node beam angle from the beam angles for communication between the first node and each secondary node.

Abstract: A method for alignment of a first node with a second node in a wireless communication network. The method comprises directing a first node first antenna beam at a first pointing angle, using a second node antenna beam for scanning a first volume with objects being able to generate signal reflections/diffraction, detecting a first signal property of reflected/diffracted signals; and saving scan angles resulting in said first signal property exceeding a first threshold level. The method further comprises directing the second node antenna beam at said saved angles, and, for each such angle: using a first node second antenna beam for scanning; and detecting at least a second signal property of reflected/diffracted signals; exchanging information between the nodes comprising first node second antenna beam pointing direction angles resulting in said second signal property exceeding a second threshold level and said saved angles; and selecting angles for communication.

Abstract: An antenna arrangement comprising a SIW with at least one radiating arrangement. The SIW comprises a dielectric material, a first and second metal layer and a first and second electric wall element running essentially parallel and electrically connecting the metal layers. For each radiating arrangement, the antenna arrangement comprises at least one coupling aperture in the first metal layer, and for each coupling aperture there is a third wall element running between the first and second electric wall elements, across a SIW longitudinal extension (es). For each radiating arrangement, the antenna arrangement further comprises an at least partly electrically conducting antenna component which comprises at least four radiating elements and is surface-mounted on the first metal layer, enclosing at least one coupling aperture. For each radiating arrangement, electromagnetic signals are arranged to be transmitted between said coupling aperture and said radiating elements.
