    4L5&4L1 miniaturized 8-element anti-jamming array antenna
    创始人2025-01-13

    TDXL-KGR4L5&4L1 is an 8-element anti-jamming satellite array antenna designed for supporting GPS dual-frequency L5 and L1. The antenna offers high unit gain and good consistency among anti-jamming units. It offers wide beam pattern, excellent high and low elevation performance, as well as strong capabilities against single and multiple jamming. Made from special materials, the antenna is equipped with a low-profile design, allowing for better integration with customer’s terminal products. The antenna with special craft makes it possible to resist extreme temperature fluctuation and corrosion. It can be widely applied in shipborne, ship-mounted, vehicle-mounted and other various fields.

    1、The antenna's anti-jamming units are symmetrically designed, ensuring consistent gain for each unit；

    2、It features a high degree of isolation between unit ports;

    3、It offers excellent circular polarization axial ratio and gain bandwidth;

    4、The antenna’s laminated design reduce its overall size and weight;

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