摘要： An antenna assembly (10) includes a substrate (24) and an array of antenna elements (26). Each antenna element is supported by the substrate at respective locations so that the antenna elements are arranged in space in a helix pattern (28). The helix pattern has a pitch along an axis about which the helix pattern turns. An arc length spacing of the antenna elements along the helix pattern and the pitch are arranged so that, in a transmit mode, a radio frequency (RF) signal fed to each of the antenna elements results in emission of a radiated signal with a rotational wave front from the antenna assembly at a first frequency and a first mode.

摘要： A method of operating a wireless communication device (102) connectable to a communications network (100) includes participating in a transmission of payload data between the communications network and the wireless communication device using a first transmit beam (511). The method also includes selecting a second transmit beam (512) for performing a calibration of one or more radio frequency components of the wireless communication device during an uplink calibration gap (322) while the transmission of the payload data is suspended. The second transmit beam is selected to differ from the first transmit beam to thereby reduce a risk that the calibration causes interference to other devices (101, 103, 104).

摘要： A re-configurable repeater device – such as a large intelligent surface or an amplify- and-forward repeater – includes an array of reflective elements and a beam-shaping unit in front of the array. The beam-shaping unit is configured to increase a beam diameter of an incoming beam. For instance, the divergence of incoming electromagnetic waves can be increased. It would be possible that the beam-shaping unit is im- plemented as a lens, e.g., a Luneberger-type lens.
