11. Layout Guide
1. All traces can fan out directly.
2. To have basic radiation performance. Recommend to keep antenna area (below red block, 11.0 mm
x 4.2 mm) clean and 5 mm extended.
3. To have better radiation performance, more clearance area is needed. Recommend to keep any
metal out from antenna clearance and 20 mm extended.
4. Thickness of system board will make antenna resonant frequency shift. Recommend thickness of
system board is 1.0mm which resonant frequency is 2.5GHz. Resonant frequency will be close to
2.45GHz after assembly in plastic housing.
