摘要： A multi-column antenna having ports for different sub-bands is provided. In one aspect of the invention, power dividers couple the sub-band ports to the columns of radiating elements. At least one power divider is an un-equal power divider to allow a half-power beam width (HPBW) of one sub-band to be configured independently of the HPBW of the other sub-band. The ports may be combined at the radiating elements by diplexers. According to another aspect of the present invention, a multi-column antenna has a plurality of first sub-band ports and a plurality of second sub-band ports. Each of the first sub-band ports is coupled to one of the columns by a first sub-band feed network. Each of the second sub-band ports is coupled to two of the columns by a second sub-band feed network including a power divider. The different sub-bands have different MIMO optimization of the same multi-column antenna.

摘要翻译： 提供了具有用于不同子带的端口的多列天线。 在本发明的一个方面，功率分配器将子带端口耦合到辐射元件的列。 至少一个功率分配器是不相等的功率分配器，以允许一个子带的半功率波束宽度（HPBW）独立于另一子带的HPBW来配置。 端口可以通过双工器在辐射元件处组合。 根据本发明的另一方面，多列天线具有多个第一子带端口和多个第二子带端口。 第一子带端口中的每一个通过第一子带馈送网络耦合到列之一。 第二子带端口中的每一个通过包括功率分配器的第二子带馈送网络耦合到两列。 不同的子带具有相同的多列天线的不同的MIMO优化。
