  • BASE STATION ANTENNAS HAVING CALIBRATION CIRCUIT CONNECTIONS THAT PROVIDE IMPROVED IN-COLUMN AND/OR ADJACENT CROSS-COLUMN ISOLATION
    Publication number: 20230291121
    Abstract: A base station antenna includes a calibration circuit that has a plurality of pairs of directional couplers and an antenna array that includes a plurality of columns of radiating elements. The first polarization radiators of the radiating elements in each column are electrically connected to a first directional coupler of a respective one of the pairs, and the second polarization radiators of the radiating elements in the column are electrically connected to a second directional coupler of the respective one of the pairs. The directional couplers may be arranged in a manner that reduces in-column coupling and/or that reduces cross-column coupling between adjacent columns of radiating elements.
