摘要：本发明涉及一种高频辐射单元与多频基站天线，高频辐射单元包括辐射体、振子座以及第一馈电件与第二馈电件。由于第一竖向段与中心线的间距大于第一巴伦与中心线的间距，第二竖向段与中心线的间距大于第二巴伦与中心线的间距，即第一竖向段布置于第一巴伦远离于中心线的一侧，第二竖向段布置于第二巴伦远离于中心线的一侧，这样并非是如同传统技术中将第一竖向段、第二竖向段均分别布置于第一巴伦、第二巴伦的内部走线槽中，从而便无需如传统技术中设置封闭式的巴伦结构，而是可以设置为开放式的巴伦结构，进而能一定程度地减小振子座的结构尺寸，即能使得实现振子座的小型化，同时能减小巴伦的寄生辐射，有效提升高频辐射单元的增益。

摘要： A reflector sub-assembly for an antenna assembly configured to support FDD and TDD modes of operation is presented. The reflector sub-assembly comprises a reflector defining at least one reflector opening. The reflector sub-assembly further comprises at least one first printed circuit board (PCB) arranged to cover the at least one reflector opening so as to prevent electromagnetic radiation from passing through the at least one reflector opening.

摘要： Systems and methods derive spatial information associated with an object that is deployed in association with at least one beacon or at least one interrogation unit. The at least one beacon has a reflector antenna that has an adjustable internal impedance, and an impedance modulation unit that varies the internal impedance of the reflector antenna such that the reflector antenna produces impedance-modulated reflected signals in response to impinging interrogation signals. The at least one interrogation unit transmits an interrogation signal to impinge upon the reflector antenna, and receives reflected signals from the reflector antenna. A processing unit is associated with the at least one interrogation unit and processes the reflected signals received by the at least one interrogation unit to derive the spatial information.

摘要： A reflectarray for an antenna system for use in wireless communications is described. The reflectarray includes a substrate and a plurality of cells configured in an array on the substrate. Each cell in the plurality of cells includes three dipoles arranged in a parallel configuration with a length of a center dipole is longer than a length of a lateral dipole. The length of the lateral dipole is 65% of the length of the center dipole. The plurality of cells can include a first set of three parallel dipoles arranged in a first direction and a second set of three parallel dipoles in a second direction that is orthogonal to the first direction. The first set of three parallel dipoles and the second set of three parallel dipoles are shifted half a period along both the first direction and the second direction in the array.
