    Abstract: A method of configuring an antenna that includes a plurality of RET units that are associated with respective ones of a plurality of arrays of radiating elements is provided in which, for each array in a subset that includes at least one of the arrays, setting an output of the RET unit associated with the array to a position that corresponds to a pre-selected electronic downtilt for the array. A first RET unit configuration file is loaded into a memory of the antenna, where the first RET unit configuration file does not include configuration data for the RET units associated with the arrays that are included in the subset. A second RET unit configuration file is provided that includes configuration data for all of the RET units.

    Abstract: Base station antennas include a first array that has a plurality of columns of radiating elements. All of the columns in the first array except for a first column and a second column are spaced apart from adjacent of the columns of the first array by a first distance. The first and second columns of the first array are spaced apart from each other a second, larger distance (e.g., twice the first distance) to define a first column-shaped open space within the first array. A column of a second array may be positioned in the first column-shaped open space within the first array.

    Abstract: Base station antennas include a plurality of multiplexer filters and a multi-column array of radiating elements that includes a plurality of sub-arrays. Each filter may have a first and second ports that are configured to pass RF signals in respective first and second frequency bands and a third common port that is coupled to a respective one of a plurality of sub-arrays. These antennas also include first frequency band ports that are coupled to the first ports of respective subsets of the multiplexer filters and second frequency band ports that are coupled to the second ports of at least some of the multiplexer filters. The antenna may operate as a MIMO sector antenna in the first frequency band and as a sector-splitting antenna in the second frequency band.

    Abstract: Base station antennas are provided that include a first array of radiating elements that is configured to form a first antenna beam that has a first downtilt angle in response to a first RF signal that is input at the first RF port and a second array of radiating elements that is configured to form a second antenna beam that has a second downtilt angle in response to a second RF signal that is input at the second RF port. The second downtilt angle is less than the first downtilt angle. The first antenna beam is configured to only provide coverage to users within a first portion of a coverage area of the base station antenna that is close to the base station antenna and the second antenna beam is configured to provide coverage to users within a second portion of the coverage area that extends farther from the base station antenna than does the first portion.

    Abstract: A lensed base station antenna includes a first array that includes a plurality of first radiating elements that are configured to transmit respective sub-components of a first RF signal, a second array that includes a plurality of second radiating elements that are configured to transmit respective sub-components of a second RF signal and an RF lens structure positioned to receive electromagnetic radiation from a first of the first radiating elements and from a first of the second radiating elements. A first subset of the first radiating elements are aligned along a first vertical axis and a second subset of the first radiating elements are aligned along a second vertical axis that is spaced apart from the first vertical axis. The first and second arrays each include a single radiating element per horizontal row.

    Abstract: A base station antenna (BSA) system includes a radio-frequency (RF) generator having a plurality of power-amplifying circuits therein, and an antenna, which includes a plurality of columns of radiating elements. These radiating elements are electrically coupled by RF signal routing to a corresponding plurality of ports of the antenna that receive a corresponding plurality of RF input signals. These RF input signals have respective amplitudes and phases that support the concurrent generation of three spaced-apart RF beams by the antenna and are derived from respective RF signals generated by the plurality of power-amplifying circuits. The RF input signals including: (i) a first RF input signal defined by at least two linearly superposed RF signals of equivalent frequency having unequal combinations of amplitude and phase weighting, and (ii) a second RF input signal defined by at least two linearly superposed RF signals of equivalent frequency having unequal combinations of amplitude and phase weighting.

    Abstract: Printed circuit boards for a base station antenna include a substrate layer, and a first conductive trace and a second conductive trace which are printed on the substrate layer and cross each other. The first conductive trace has two trace sections separated by the second conductive trace. Adjacent ends of the two trace sections separated by the second conductive trace are connected electrically by a jumper. The jumper has an electrical conductor, is isolated electrically from the second conductive trace and is fixed on the printed circuit board. The electrical conductor and the two trace sections are connected electrically at adjacent ends. The printed circuit board allows flexible wiring of the conductive traces on the printed circuit board.
