    Twelve-element anti-jamming array antenna
    创始人2025-01-15

    TDXL-KGR12 7I05 is a full-band anti-jamming antenna, which effectively suppresses low elevation angle signals through the rational layout of twelve full-band spiral antenna elements, thereby achieving low elevation angle interference resistance. The antenna has excellent circular polarization characteristics and high consistency between elements. The array synthesis results in high top gain and a high roll-off factor, offering the antenna excellent low elevation angle interference resistance capabilities. The single antenna element with special craft makes it possible to resist extreme temperature fluctuation, corrosion, and UV rays. It can be widely applied in UAVs, shipborne, ship-mounted, vehicle-mounted and other various fields.

    1、The antenna unit adopts a multi-arm spiral structure, and each single antenna exhibits excellent circular polarization characteristics.

    2、The appropriate spacing ensures a high degree of isolation between unit ports;

    3、Excellent top reception gain and roll-off characteristics, ensure that the antenna has excellent resistance to low elevation angle interference;

    4、It can be flexibly customized in terms of operating frequency, size, and structure according to customer’s requirements.

    5、Lightweight design, suitable for use on equipment with low elevation angle anti-interference requirements on the ground.
