  • Publication number: 20190081407
    Abstract: An integrated antenna unit where two dual-polarized radiating elements are connected on a PCB serving reflecting board as well as a filter lid of two-band pass filters. Each of two band-pass filter is connected directly to a two-way power splitter serving connection of same polarization from the two radiating elements. Two walls running parallel are extending at the band-pass filter edges to support the cavity of the filters and at same time serving as reflecting walls enabling to control the 3 dB azimuth beam generated by the radiating elements. Next, a multi-array antenna by collocating multiple arrays of the integrated antenna units.

  • Patent number: 9385432
    Abstract: A wideband dual-polarized radiation element includes two pairs of cross polarized dipoles and baluns which correspondingly feed current to each dipole in a balanced manner. Each dipole includes a pair of unit arms aligned on a top end of the corresponding balun. One end of each unit arm is connected on top of the balun, and the other end of one unit arm is bending inwards to form inward loaded line, and the other unit arm is bending downwards to form downward loaded line. An antenna includes a metal reflector and at least one wideband dual polarized radiation element, which has excellent radiation and polarization performance.

  • Patent number: 8941549
    Abstract: A compact four-way transducer (FWT) is provided for a microwave communications system. The compact FWT is a compact assembly that is configured to process microwave signals in dual-polarization antenna feeds and to provide single polarized signals for four communications channels. The compact FWT includes four terminals facing different directions at one end for receiving/sending single polarized signals, and a terminal at an opposite end for receiving/sending dual polarized signals.
