    Built-in BDS short message reception antenna specification
    创始人2025-01-15

    TDXL-BSA504-B is a BDS short message reception antenna, designed with multi-feed microstrip technology, supporting the reception of BDS short message signals in the S-band. It could widely applicable in portable equipment, handheld terminals that require short message reception capabilities.

    1、Using multi-feed miniaturized design, the antenna enables the right circular polarization and phase center performance, as well as minimizes the impact of measuring error.

    2、The antenna unit offers high gain and minimal gain roll-off, providing excellent reception of low elevation satellite signals and ensuring normal reception in severely obscured locations.

    3、The pre-filter circuit design can effectively reduce interference with signal reception, ensuring measurement accuracy.
