Figure 7-5 shows the layout of the 2.4G ceramic chip antenna. SLDA52-2R540G-S1TF is used as an
example.
Figure 7-5
Antenna layout
If the PCB is large enough, you can adopt the layout shown in Figure 7-5 (a).
1 Chip antenna
2 Feeder
3 Pad of the matching circuit
4 50Ω transmission line (calculated using Si9000
or APPCAD)
Number 5 in Figure 7-5 shows the area between the antenna and the ground Figure 7-6 shows the
clearance if this area.

Clearance around the antenna
For more details, refer to the antenna manufacturer's product documents.
On the PCB, keep the RF signals and RF components away from high-speed circuits, power supplies,
transformers, inductors, the clock circuit of single-chip host, etc.
