    11-element anti-jamming array antenna-4B3+4S+L+B1/L1+GLN
    创始人2025-01-13

    TDXL-KGR1101 is a 11-element anti-jamming array antenna designed for BDS 4B3 and 4S anti-jamming, while also receiving navigation satellite signals from B1I, B1C, L1 and GLONASS system, as well as transmitting BDS L-band signals. 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 ratio and gain bandwidth;

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