Abstract
Base station antennas are provided. A base station antenna includes a first array of radiating elements and a second array of radiating elements that is interleaved with the first array. Each of the first and second arrays has a plurality of non-rectangular sub-arrays that include radiating elements in one or more outer columns and radiating elements in an inner column that is between the first and second outer columns.
Claims19
A base station antenna comprising:
- a first antenna array having a vertical stack of first sub-arrays that each comprise a plurality of first-band radiating elements;
- and
- a second antenna array having a vertical stack of second sub-arrays that each comprise a plurality of first-band radiating elements,
- wherein the first sub-arrays share a vertical column of first-band radiating elements with the second sub-arrays, and
- wherein the first-band radiating elements that are in the shared vertical column are configured to have a fixed phase delay applied thereto that is different from fixed phase delays of the first-band radiating elements of portions of the first and second sub-arrays that are outside of the shared vertical column.

A base station antenna comprising:
- a first outer column of radiating elements of a first array, the first array comprising a plurality of first non-rectangular sub-arrays;
- a second outer column of radiating elements of a second array, the second array comprising a plurality of second non-rectangular sub-arrays;
- an inner column of radiating elements that is shared by the first and second arrays and is between the first and second outer columns;
- and
- a plurality of power dividers, the power dividers comprising first power dividers that are coupled to the first non-rectangular sub-arrays, respectively, and second power dividers that are coupled to the second non-rectangular sub-arrays, respectively,
- wherein a first of the first non-rectangular sub-arrays comprises first through third radiating elements,
- wherein the first and second radiating elements are in the first outer column and are coupled by first and second radio frequency (RF) transmission lines, respectively, to a first of the first power dividers,
- wherein the first and second RF transmission lines have different first and second lengths, respectively, and
- wherein the third radiating element is in the inner column and is coupled to the first of the first power dividers by a third RF transmission line having a third length that is longer than each of the first and second lengths.
