    摘要: A communication system can comprise an ordered arrangement or array of two sets, groups, or groups of antenna elements. The system can transmit or receive two bands or ranges of electromagnetic energy, signals, or radiation. The first set of the antenna elements can operate one of the bands, while the second set can operate the other band. The first set of antenna elements can be arranged or disposed to form a line or a column. The second set of antenna elements can be arranged or disposed on opposite sides of the line, with some of those elements on one side of the line and the remainder on the other side. The antenna elements that are on one side of the line can be staggered or longitudinally offset with respect to the antenna elements that are on the opposite side of the line.

    摘要: A dual-polarization wireless base station antenna that implements vertical electrical downtilt and sidelobe reduction using beam steering circuit that includes a variable power divider and a multi-beam beam forming network. The variable power divider includes a single adjustable control element to divide an input voltage signal into a pair of complimentary amplitude voltage drive signals that exhibit matched phase and constant phase delay through the variable power divider. The beam forming network is configured as a double-sided, edge-connected microstrip module mounted to a main panel, which support the antenna elements in a vertical column organized into sub-arrays in a manner that implements sidelobe reduction. The power distribution network connecting the beam steering network to the antenna elements implements beam tilt bias and sidelobe reduction through coordinated phase shifting implemented through transmission media trace length adjustment.

    摘要: A wiper-type variable power divider with capacitive junctions to minimize the creation of passive intermodulation interference (PIM) during adjustment of the power divider. The variable power divider includes an adjustable, wiper-type phase shifter connected to a hybrid power divider. The output ports of the hybrid power divider produce two RF signals having variable and complementary power amplitudes as the power divider is adjusted throughout its adjustment range. The power divider output signals also have a sum that is substantially equal to a constant quantity throughout the adjustment range of the power divider. The phase shifter is well suitable for use in a base station antenna, where it can be used for be beam steering and beam width adjustment. The variable power divider can also be operated by remote control of a motorized actuator that operates the power divider.

    摘要: Wireless repeaters that utilize balanced and quasi-balanced antenna feed circuits for feedback suppression. The wireless repeater typically implements dual cross-polarization isolation both along and between uplink and downlink signal paths, which relies on dual-polarization server and donor antennas. The unit may utilize balanced antenna feeds for both polarizations or balanced antenna feeds for one polarization and unbalanced antenna feeds for the other polarization. In addition, the unbalanced antenna feeds may be deployed in a two-element quasi-balanced configuration, and the antenna may include dual-polarization antenna element. The antenna elements may include dual-polarization antenna elements or separate antenna elements for each polarization.

    摘要: A wireless repeater that includes a universal server base unit and modular donor antenna options. The universal server base unit includes a base unit bidirectional amplifier, a server antenna, and a housing that accepts an internal donor antenna board or an internal adapter module connected to a cable port for receiving a coaxial cable connected to an external donor antenna. This allows the same universal server base unit to work with a variety of internal and external donor antenna options. In particular, the external donor antennas include outdoor swivel-mounted options including a helical circular polarization antenna, a dual polarization panel antenna, and a vertical polarization panel antenna. The donor antenna may include an optional donor bidirectional antenna located in or near the donor antenna and powered via the cable from the server base unit.

    摘要: A substantially planar antenna configured for easy installation in a ceiling or ceiling tile. The antenna is configured for duplex communications in carrier frequency ranges spanning at least a 2:1 ratio of frequency values from the highest to the lowest frequency in the carrier frequency band, such as the frequency range from 800 to 960 MHz and 1700 to 2400 MHz, and within a coverage pattern below the ceiling extending through 360° azimuth and 180° elevation. The antennas are manufactured as a printed circuit board that snaps apart into a number of panels, which each contains at least a planar antenna element and a cross brace that are used to assemble the antenna. The printed circuit board is a dielectric substrate carrying printed conductor including a radiating circular monopole disc radiating element, associated transmission signal paths, and printed indicia that typically include assembly instructions and a logo. The printed circuit board sheet configuration makes the antennas inexpensive to mass produce and easy to snap apart into individual units, which are themselves self-contained, easy to snap apart and install.
