Abstract
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.
