Abstract

A base station antenna comprises first and second RF ports, first and second columns of radiating elements that each extend in a longitudinal direction, and a power coupling circuit. A first radiating element in the second column is coupled to the first RF port via the power coupling circuit, and the phase of the RF signal fed to the first radiating element in the second column is not advanced as compared to the phase of the RF signal fed to the first radiating element in the first column. A second radiating element in the first column is coupled to the second RF port via the power coupling circuit, and the phase of the RF signal fed to the second radiating element in the first column is not advanced as compared to the phase of the RF signal fed to the second radiating element in the second column.

6 more elements

A base station antenna, comprising:

a reflecting plane extending in a longitudinal direction;
and
an array positioned in front of the reflecting plane, the array comprising:
a column formed by a plurality of first radiating elements arranged in the longitudinal direction, where the column is a first distance from a first side edge of the reflecting plane and a second distance from a second side edge of the reflecting plane, where the first distance is not equal to the second distance so that a first radiation beam generated by the column has a first squint angle in the azimuth plane;
and
a second radiating element positioned on one side of the column, where the second radiating element is configured such that there is a phase difference between the RF signal fed thereto and the RF signal fed to a corresponding first radiating element in the column, so that a second radiation beam generated by the array has a second squint angle in the azimuth plane that is less than the first squint angle.
