The PCB antenna is embedded into the PCB board during manufacturing and the ceramic chip
antenna is mounted to the PCB after the design phase is completed.
They are used only for WLAN or Bluetooth because they cannot cover wide frequencies.
Figure 4-24 shows the layout of the 2.4G ceramic chip antenna. SLDA52-2R540G-S1TF is used as an
example.
Figure 4-24 Antenna layout
If your PCB is large enough, you can adopt the layout shown in Figure 4-24 (a).
1 Chip antenna
2 Feeding mark
3 Layout pad of the matching circuit
4 50Ω transmission line
5 Space between the antenna and ground area.
Figure 4-25 shows the layout of this area.
