    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 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 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: A low sidelobe beam forming method and dual-beam antenna schematic are disclosed, which may preferably be used for 3-sector and 6-sector cellular communication system. Complete antenna combines 2-, 3- or -4 columns dual-beam sub-arrays (modules) with improved beam-forming network (BFN). The modules may be used as part of an array, or as an independent 2-beam antenna. By integrating different types of modules to form a complete array, the present invention provides an improved dual-beam antenna with improved azimuth sidelobe suppression in a wide frequency band of operation, with improved coverage of a desired cellular sector and with less interference being created with other cells. Advantageously, a better cell efficiency is realized with up to 95% of the radiated power being directed in a desired cellular sector.
