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.

Abstract: A feed network for use with an antenna array includes at least first and second RF inputs, a combiner network and a beamforming network. In some examples, additional RF inputs are provided. Each RF input corresponds to a sub-band. The first RF input for a first sub-band signal is coupled to a first sub-band parameter control; the second RF input for the second sub-band signal is coupled to a second sub-band parameter control. The combiner network is coupled to the first sub-band parameter control and to the second sub-band parameter control. The combiner network also has at least one output comprising a combination of the first sub-band signal and the second sub-band signal. The beamforming network is coupled to the combiner network and has a plurality of RF outputs. The first and second sub-band parameter controls are independently adjustable. In one example, the beamforming network comprises a Butler matrix.

Abstract: Beam forming antennas for base station applications are configured as dielectric resonator antennas (DRAs) having arrays of dielectric resonator radiating elements (DRRE) therein with dual-polarized radiating properties. Each DRRE includes a dielectric radiating element (DRE) electromagnetically coupled by a resonant cavity to a respective cross-polarized feed network, which is responsive to first and second radio frequency (RF) input feed signals. Each resonant cavity may be configured as a polymer-filled resonant cavity, and each DRE may be configured as a cylindrically-shaped or dome-shaped dielectric radiating element.

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 tilt adapter configured to facilitate a desired tilt of a first radio frequency (RF) band and a second RF band of an antenna is disclosed. The antenna supports two or more frequency bands, in which the vertical tilt of each of the supported frequency bands is separately controlled by a coarse level of phase shifting, but commonly controlled by a fine level of phase shifting.
