## **1. Introduction** 

The Taoglas SGGP.18 is a ceramic GPS/GLONASS/GALILEO passive patch antenna designed for optimal performance on GPS L1 band (1575.42 MHz) and GLONASS L1 band (1602 MHz). With a low-profile thickness of just 4mm and convenient mounting via standard SMD process, it is ideal for high-volume, low-cost assembly applications. SGGP.18 is designed for applications in navigation devices, vehicle tracking/fleet management systems, and telematics devices. It is an excellent choice for applications in transportation, defense, marine, agriculture, and navigation industries. 

This antenna has been tuned for use on a 50mm*50mm ground plane to achieve 2.86 dBi gain at 1575.42 MHz and 3.04 dBi gain at 1602 MHz. In addition to excellent efficiency, it also offers a broadly hemispherical radiation pattern with stable gain across elevations. 

SGGP.18 is manufactured and tested in an IATF16949 first tier automotive approved facility. For further optimization to customer-specific device environments, custom tuned patch antennas can be supplied, subject to NRE and MOQ.

## **6. Antenna Recommended Soldering Conditions** 

## **6.1. Flux, Solder** 

- Use rosin-based flux. Don’t use highly acidic flux with halide content exceeding 

- 0.2wt%(chlorine conversion value). 

- Use Sn solder. 

## **6.2. Reflow soldering conditions** 

- Pre-heating should be in such a way that the temperature difference between solder 

and product surface is limited to 150℃ max. Cooling into solvent after soldering also 

should be in such a way that temperature difference is limited to 100℃ max. 

Unwrought pre-heating may cause cracks on the product, resulting in the deterioration of products quality. 

## **6.3. Reworking with soldering iron** 

- The following conditions must be strictly followed when using a soldering iron.
