    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.

    Abstract: A base station antenna includes a first set of radiating elements that are configured to generate a first antenna beam that has a first peanut-shaped antenna pattern in an azimuth plane and a second set of radiating elements that are configured to generate a second antenna beam that has a second peanut-shaped antenna pattern in the azimuth plane. A longitudinal axis of the first peanut-shaped antenna pattern in the azimuth plane is rotated approximately ninety degrees from a longitudinal axis of the second peanut-shaped antenna pattern in the azimuth plane.

    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: A multi-band antenna system includes an array of wide-band radiating elements and a multi-band electrical tilt circuit. The multi-band electrical tilt circuit includes a plurality of combiners, a first RF band variable phase shifter and a second RF band variable phase shifter implemented in a common medium. The common medium may comprise a PCB, a stripline circuit, or the like. Each combiner includes a combined port, a first RF band port, and a second RF band port. The combined ports are coupled to the radiating elements. The first RF band phase shifter has a first plurality of variably phase shifted ports connected to the first RF band ports of the combiners via transmission line, and the second RF band phase shifter has a second plurality of variably phase-shifted ports connected to the second RF band ports of the combiners via transmission line. The phase shifters are independently configurable.
