Abstract: The invention provides a method of adjusting a principal communication direction of a steerable directional antenna for communicating with a terrestrial electromagnetic signal source, the method comprising: providing location specific steering data comprising one or more steering data portions, each of the steering data portions being specific to a respective location; determining a location of the steerable directional antenna; selecting a steering data portion from the location specific steering data taking into account the determined location of the antenna; determining an adjusted principal communication direction of the steerable directional antenna taking into account the said selected steering data portion; and adjusting the principal communication direction of the steerable directional antenna in accordance with the said adjusted principal communication direction.

Abstract: An antenna element (100) comprises an active patch formed by a conductive layer (104) on a front surface of a substrate (102) and a parasitic ground patch (106) on a back surface of the substrate. The active patch has a spiral slot (112) in a central portion, and peripheral portions (110a-110d) which are substantially wider than the spiral slot. A signal feed strip (114) extends from a side of said active patch across the front surface of the substrate. Two signal ground strips (116, 118) are provided on the front surface, each separated from the active patch by a predetermined gap (120, 122). The parasitic ground patch has a slot in a central portion substantially back-to-back with the central portion of the active patch through the substrate. The element has broadband properties that can be tuned by various modifications. Several elements can be used in close array, with lower cross-talk than known antenna designs.

Abstract translation: 天线元件（100）包括由衬底（102）的前表面上的导电层（104）和衬底背面上的寄生接地片（106）形成的有源贴片。 活动贴片在中心部分具有螺旋槽（112），以及比螺旋槽宽大的周边部分（110a-110d）。 信号馈送条（114）从所述活性贴片的侧面延伸穿过衬底的前表面。 两个信号接地条（116,118）设置在前表面上，每个与活动贴片分开预定间隙（120,122）。 寄生接地片在中心部分上具有大致背靠背的有源片穿过衬底的中心部分的槽。 该元件具有宽带属性，可以通过各种修改进行调整。 几个元件可以紧密地使用，具有比已知天线设计更低的串扰。
