    摘要： The invention relates to a coaxial-impedance synthesizer, comprising: a longitudinal central (0x) conductor (1); an outer conductive tube (2) arranged coaxially to the conductor (1); and at least one probe (4) mounted so as to longitudinally translate around the conductor (1), the coaxial-impedance synthesizer being characterized in that the outer tube (2) includes two separable half-tubes, such that the probe (4) is permitted to move longitudinally, relative to the central conductor (1), to a desired position when the two half-tubes are spaced apart from each other, and when the two half-tubes are near each other, the outer periphery of the probe (4) and the inner wall of the outer tube are in contact with each other.

    摘要： The present invention relates to a device (1) for transmitting or receiving electromagnetic waves in a cavity (3), where the device comprises a loop (10) and a dielectric part (9) that houses at least a first end part (11) of the loop. The dielectric part comprises a first recess (37) designed to receive a means (30) for setting the capacitance between the loop and an earthed cavity housing (5), cover (6) or casing (2) for electric and/or electronic components. The invention also relates to a method for manufacturing the device, a method for manufacturing the loop, a cavity filter (4) and the casing.

    摘要： An antenna for communicating with mobile devices in a land-based cellular communication system via an antenna beam having a width, azimuth angle and downtilt angle. The antenna includes:

    a two dimensional array of radiating elements (31-34); and
    a feed network (35-39) from a feed line to the radiating elements.

    The feed network includes:

    downtilt phase shifting means (35,36) for varying the phase of signals supplied to or received from the radiating elements so as to vary the downtilt angle of the antenna beam;
    azimuth phase shifting (38,39) means for varying the phase of signals supplied to or received from the radiating elements so as to vary the azimuth angle of the antenna beam; and
    beam width adjustment means (37) for varying the power or phase of signals supplied to or received from the radiating elements so as to vary the width of the antenna beam.

    摘要： A variable power divider and method can vary the RF power between ports in a high power and multi-carrier RF environment, such as is used in controlling signals sent and received in a base station antenna. The variable power divider can include a single-control phase shifter (110) and a hybrid power divider (115). The single-control phase shifter can comprise a three-port device having a single input port and two output ports. The single-control phase shifter can further comprise a variable adjuster that can change or adjust the phase between two RF signals. The hybrid power divider can comprise a four-port device having two input ports and two output ports. Both the single-control phase shifter and the hybrid power divider can comprise substantially planar structures that are suitable for high-speed manufacturing. The output ports of the hybrid power divider can be coupled to various devices such antennas or power absorbing elements.
