Abstract:
Methods for aligning base station antennae at a cell site, the base station antenna which may include a first antenna, a second antenna, and a third antenna, each providing coverage of a respective sector of the cell site, may involve taking measurements of signals received in regions of antennae coverage overlap and adjusting azimuth angles of one or more of the antennae to substantially equalize received signal strengths.
Abstract:
Array antennas include a plurality of lensed multi-beam sub-arrays, where each lensed multi-beam sub-array comprises a RF lens and a plurality of radiating elements that are associated with the RF lens and that are orbitally arranged about the RF lens.
Abstract:
Phased array antennas include a plurality of radiating elements and a plurality of RF lenses that are generally aligned along a first vertical axis. Each radiating element is associated with a respective one of the RF lenses, and each radiating element is tilted with respect to the first vertical axis.
Abstract:
There is provided a cellular antenna allowing mechanical azimuth adjustment in combination with adjustment of one or more other antenna attribute such as electrical down tilt, electrical beam width or electrical azimuth adjustment. An integrated control arrangement is provided which can utilize either serial, wireless or RF feed lines to convey communications. A multiband embodiment provides azimuth adjustment for both bands by utilizing mechanical and electrical azimuth adjustment. Systems incorporating such antennas and methods of controlling them are also provided.
