    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.

    Abstract: A millimeter-wave antenna arrangement (1) comprising at least one first antenna array (2), said first antenna array (2) comprising a plurality of antenna elements (2a) such as patch antennas, and an artificial dielectric structure (3) superposed over said first antenna array (2). Said artificial dielectric structure (3) comprises a plurality of conductor layers (4) separated by dielectric layers (5), each conductor layer (4) comprising a plurality of periodically repeated conductor patterns (6). One conductor pattern (6) of each conductor layer (4) is associated with one of said antenna elements (2a), and the conductor patterns (6) associated with one antenna element (2a) are at least partially non-identical. Said artificial dielectric structure (3) has an artificial dielectric constant, and each dielectric layer has a natural dielectric constant, said artificial dielectric constant depending at least partially on the natural dielectric constants and preferably having a value between 10-30.
    This configuration provides a way of achieving multi-surface beam coverage, e.g. by means of end-fire antenna elements as well as broadside antenna elements, while maintaining a compact footprint.

    Abstract: A millimeter-wave (mmWave) assembly (1) comprising a first mmWave module (2), a second mmWave module (3), and a connector (4) configured to releasably interconnect the first mmWave module (2) and the second mmWave module (3). The connector (4) comprises a first connector element (5) associated with the first mmWave module (2). The first mmWave module (2) comprises a first substrate (7) and an mmWave radio frequency integrated circuit (RFIC) (8), and the second mmWave module (3) comprises a second substrate (9) and an mmWave antenna array (10). The connector (4) is configured to transmit at least one signal between the mmWave RFIC (8) and the mmWave antenna array (10) when the first mmWave module (2) and the second mmWave module (3) are interconnected.

    Abstract: A redirection structure for electromagnetic waves includes a multilayer structure and at least one antenna element. The multilayer structure includes a first conductive element, a conductive substrate, and a dielectric substrate arranged between the first conductive element and the conductive substrate and forming a wave guide. The antenna element is arranged adjacent an edge of the multilayer structure at an interface, the electromagnetic waves at least partially propagating in the wave guide along a first direction. The redirection structure further includes at least one dielectric cavity arranged at a predefined distance from the interface along the first direction. The dielectric cavity extends in a second direction away from the dielectric substrate at least partially through the conductive substrate.
