    • An antenna arrangement including at least two antenna functions arranged to cover a certain angular sector, each antenna function comprising a corresponding antenna port. The antenna arrangement is configured to perform: a first direction of arrival (DOA) estimation for a transmitting device at a first frequency, and a second DOA estimation for the transmitting device at a second frequency, wherein the second frequency has a larger magnitude than the first frequency, and wherein at least one second frequency grating lobe is apparent in the angular sector at the second frequency. The antenna arrangement is configured to: distinguish the at least one second frequency grating lobe from a second frequency main lobe using results from the first DOA estimation, and identify a pointing direction of the second frequency main lobe as a resulting DOA estimation. Related methods are also described.

    • Aspects and embodiments described may provide a method of counteracting misalignment caused by movement of at least one node (20, 40) supporting a communication link in a point to point communication network, a computer program product and network node operable to perform that method. The method comprises: providing a substantially planar antenna array (200; 500) comprising a plurality of radiating elements (210; 510); arranging the radiating elements (210; 510) to be spaced apart in accordance with a pre-selected centre signal feed wavelength; arranging a signal feed line to feed a signal to the radiating elements (210; 510) such that, at said pre-selected wavelength, the antenna array beam direction is perpendicular to a surface of the substantially planar antenna array (200; 500);
      receiving an indication that misalignment caused by movement of at least one node (20, 40) supporting the communication link in a point to point communication network is occurring; and adjusting the centre signal feed wavelength in dependence upon said indication to steer the antenna array beam direction to counteract the movement of the at least one node (20, 40) supporting the communication link. Aspects recognise that it may be desirable to provide a point to point communication system with a mechanism which can operate to adjust a beam direction, at least at one end of a radio link, in a manner which allows for counteraction of normal occurrences of changes of antenna orientation. In other words, a mechanism which can counteract changes of antenna orientation with appropriate changes of beam direction. Such a mechanism may operate such that counteraction can occur in real time.
    • 所描述的方面和实施例可以提供一种抵消由点对点通信网络支持通信链路的至少一个节点(20,40)的移动引起的未对准的方法,可操作以执行该方法的计算机程序产品和网络节点。 该方法包括:提供包括多个辐射元件(210; 510)的基本上平面的天线阵列(200; 500); 根据预先选择的中心信号馈送波长将辐射元件(210; 510)布置成间隔开; 布置信号馈送线以将信号馈送到所述辐射元件(210; 510),使得在所述预选波长处,所述天线阵列波束方向垂直于所述基本上平面的天线阵列(200; 500)的表面; 接收指示发生在点对点通信网络中支持通信链路的至少一个节点(20,40)的移动引起的未对准的指示; 以及根据所述指示调整所述中心信号馈送波长,以引导所述天线阵列波束方向以抵消支持所述通信链路的所述至少一个节点(20,40)的移动。 方面认识到,可能希望提供一种具有机制的点对点通信系统,该机制可以以至少在无线电链路的一端调整波束方向,其方式允许对正常出现的变化进行抵消 天线方位。 换句话说,一种能够适应波束方向变化来抵消天线方位变化的机构。 这样的机制可以进行操作,使得反作用可以实时发生。

    • An antenna system for radar sensors, for example in vehicles (automatic adaptive cruise control system (ACC)), having at least one planar group antenna (10) which comprises a feed line (14) and a plurality of antenna elements (16, 18) which are integrated into the feed line. The group antenna (10) has at least two antenna gaps (20, 22) which run parallel to one another and which are connected to one another at one end via a bypass line (24). The length of said bypass line (24) is dimensioned such that the antenna gaps are overall in phase with one another. The power which still remains at the end of the first antenna gap does not need to be reflected but instead is irradiated via the antenna elements of the second antenna gap. The phase and amplitude assignments are selected such that the directional characteristic is improved.
