Lensed sector-splitting multiband base station antennas where the number of beams per frequency band is not related by the frequency ratio between the frequency bands

A multiband, multibeam base station antenna, comprising:

• one or more radio frequency (“RF”) lenses;
• a plurality of first RF ports;
• a plurality of second RF ports;
• a plurality of arrays of first radiating elements, each array of first radiating elements coupled to a respective one of the RF ports in the plurality of first RF ports and including at least one first radiating element, where the first radiating elements are configured to operate in a first frequency band and are positioned to transmit RF signals through the one or more RF lenses;
• and
• a plurality of arrays of second radiating elements, each array of second radiating elements coupled to a respective one of the RF ports in the plurality of second RF ports and including a plurality of second radiating elements, where the second radiating elements are configured to operate in a second frequency band and are positioned to transmit RF signals through the one or more RF lenses,
• wherein a first number of arrays of first radiating elements is the same as a second number of arrays of second radiating elements, and
• each of the arrays of second radiating elements is a multicolumn array of radiating elements.

A multiband, multibeam base station antenna, comprising:

• a plurality of arrays of first radiating elements, each array of first radiating elements including at least one first radiating element, where the first radiating elements are configured to operate in a first frequency band and are positioned to transmit RF signals through the one or more RF lenses;
• and
• a plurality of arrays of second radiating elements, each array of second radiating elements including a sub-array of second radiating elements that are positioned around one of the first radiating elements in a respective one of the plurality of arrays of first radiating elements, where the second radiating elements are configured to operate in a second frequency band that encompasses higher frequencies that the first frequency band and are positioned to transmit RF signals through the one or more RF lenses.
