Revision History:

GNSS antennas are a critical but often overlooked part of a receiver setup. Choosing a correct antenna is hugely important since antennas are the main interface between the GNSS space segment and the user, as they capture the L-band signal transmitted by satellites. Antenna must be able to convert the energy in the electromagnetic waves arriving from the satellites into an electric current that is further processed by the receiver. Given that signals received from GNSS satellite are weak and arriving from any direction, it is clear that choosing the correct antenna is imperative. Choosing the optimal GNSS antenna for the application will maximize GNSS receiver’s positioning performance.

The YG-BDSP300-SMA active antenna are use JND unique technology to achieved GNSS dual band system operation, that can covering the GPS L1,L2,L5; BeiDou B1,B2 frequency band. In order to meet simple foot print layout on main board and low cost demand, JND use stack with one feed pin of antenna to generate two frequency mode, which are still shows the low axial ratio and RHCP polarization radiation performance. (The operation band of patch element can be choosing by customer demand)

In order to increase GNSS radio frequency sensitivity and signal noise ratio, YG-BDSP300-SMA uses a LNA+ Dual SAW+PD+LNA diagram, which provides excellent noise figure and high gain that is constant across the full frequency band. The final output with the SMA female connector, it’s easy to fit together with RF cable.   

The YG-BDSP300-SMA active antenna has portable and dual band features, which can use on tracker, navigation device and autonomous vehicles.
