Its small form factor makes it ideal for spaceconstrained applications such as compact telematics devices, vehicle tracking and fleet management systems, wearables, and navigation devices. The antenna is optimized for a 50mm x 50mm ground plane, operating at 1575.42 MHz with a peak gain of 1.01dBi. Designed for SMT mounting, the ceramic patch includes an additional solder mask to enhance durability and prevent cracking due to heat expansion during high-volume, cost-sensitive assembly processes. Typical applications include: - Vehicle Tracking and Fleet Management Systems - Wearables - Navigation Devices The DSGP Series can be manufactured in a TS16949 first-tier automotive-approved facility and tested to AECQ200 certification if required. Further to this, full PPAP and IMDS documentation can be provided upon request. Please discuss your quality and reliability requirements with our team prior to ordering. Taoglas also offers custom tuning services based on minimum order quantities, contact your regional Taoglas customer support team for further information. 3 www.taoglas.com SPE-25-8-110-A |**GNSS Frequency Bands**|**GNSS Frequency Bands**|**GNSS Frequency Bands**|**GNSS Frequency Bands**|**GNSS Frequency Bands**|**GNSS Frequency Bands**| |---|---|---|---|---|---| |**GPS**|**L1**

The PCB layout shown in the diagrams below demonstrates the DSGP124B clearance area. The copper keep out area applies to the top layer and all internal layers. There should be a 3mm copper clearance area around RF Feed pad. 12 www.taoglas.com SPE-25-8-110-A ## Antenna Integration The DSGP124B should be placed at the centre of the PCB, to take advantage of the ground plane. The RF trace must maintain a 50 Ohm transmission line. Ground vias should be placed around the RF trace.
