SPE-25-8-111-A 

The SSGP124B is a compact ceramic GPS/GLONASS/GALILEO/BEIDOU passive patch antenna, measuring just 12mm x 12mm with a low-profile height of 4mm. Its small form factor makes it ideal for space-constrained 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 1575.42MHz, 1602MHz and 1561MHz with a peak gain of 0.72dBi gain, 1.17dBi gain -5.06dBi gain. 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 SSGP 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.

## Copper Clearance for SGGP124B 

The footprint and clearance on the PCB must comply with the antenna’s specification. The PCB layout shown in the diagrams below demonstrates the SGGP124B 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.

## Antenna Integration 

The SGGP124B 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.

The SGGP124B can be assembled by following the recommended soldering temperatures are as follows: 

*Temperatures listed within a tolerance of +/- 10º C 

Smaller components are typically mounted on the first pass, however, we do advise mounting the SGGP124B when placing larger components on the board during subsequent reflows. 

Note: Soldering flux classified ROL0 under IPC J-STD-004 is recommended.
