GNSS Module with Patch Antenna

    The DL-HD-2528 is a complete standalone GNSS smart antenna module, including an embedded patch antenna and GNSS receiver circuits. The module can simultaneously acquire and track multiple satellite constellations that include GPS, BEIDOU, GALILEO, QZSS and SBAS. Besides, it can provide you with 

superior sensitivity and performance even in urban canyon and dense foliage environment.

It is easy to install without both RF connector and coaxial cable that are needed in a separated GNSS active antenna. In other words, reduce the cost and size. Also, speed up the time to market by eliminating R&D efforts on RF matching and stability between separated GNSS antenna and module. Its far-reaching capability meets the sensitivity requirements of car navigation as well as other location-based applications.
