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 wideband antenna includes a plurality of radiating elements arranged in an array and a feed network. The feed network includes at least one frequency dependent power divider for varying the amplitude of a signal provided to at least two of the plurality of radiating elements as a function of a frequency of a signal. The feed network may further comprise a plurality of inputs and the antenna may produce a plurality of beams. The frequency dependent divider may comprise a power divider having a first output and a second output, a 90° hybrid, having a first input coupled to the first output of the power divider, and a second input, and a delay line, coupled between the second output of the power divider and the second input of the 90° hybrid.

Abstract: A multiple beam antenna system is described. The system may include a mounting structure, a first wireless access antenna, a second wireless access antenna, and a radio frequency lens. The first and second wireless access antennas may be mounted to the mounting structure. Columns of radiating elements of the first and second wireless access antennas may be aligned with the radio frequency lens. The radio frequency lens may be modular in a longitudinal or radial direction, or in both directions. The radio frequency lens may include a plurality of compartments arranged to form a first cylinder made up of concentric, coaxial cylinders and a plurality of dielectric materials in at least some of the plurality of compartments.
