Matching Circuit (recommend for reference test board only)
For usable matching, the ground stability must be guaranteed with sufficient via holes and the case effects should be considered. Finally, using one or more lumped chip elements and a tuning stub are recommended for better results.

LAYOUT RECOMMENDATIONS
Layout
Design Guide
Placement
- Antenna should be placed to the edge of PCB.
- Place the chipset near the antenna.
- Place the matching circuit as close as possible the antenna.
- Antenna should be placed far from LCD and conducting materials like battery, EMI shielding materials, metal case, etc
