    创始人2025-01-11

    TDXL-BLS3007 is a built-in antenna designed for receiving BDS B1I, S-band satellite signals, and transmitting BDS L-band signals. It is designed with a dual-layer integrated structure to achieve miniaturization, while maintains high gain and wide beam pattern. It exhibits excellent high and low elevation performance, providing good resistance to extreme temperature fluctuation and corrosion, which can do outdoor work for a long time. The antenna is widely applied in ship-borne, vehicle-mounted, handset and other fields.

    1、The antenna part adopts symmetrical design to minimize the impact of the precision error and ensure the phase center stability.

    2、The unit features a dual-feed design, offering high gain, a wide directional beam, and excellent low-elevation signal reception, ensuring normal reception in special occasions where the signal is severely obscured.

    3、It is designed with an integrated structure to achieve miniaturization.

    4、The multi-feed structure ensures the antenna maintains excellent circular polarization and axial ratio characteristics.

    5、Compact size and easy to integrate.

    6、Can be flexible customized according to customer’s request.
