Recommended Host PCB Layout
Figure 3 details the recommended PCB layout pattern for the host PCB.
Figure 3. Recommended PCB Layout Pattern for CYBLE-01201x-x0 Module
To maximize RF performance, the host layout should follow these recommendations:
1. The ideal placement of the Cypress BLE module is in a corner of the host board with the trace antenna located at the far corner.
This placement minimizes the additional recommended keep out area stated in item 2.
2. It is recommended that the area around the Cypress BLE module trace antenna should contain an additional keep out area, where
no grounding or signal trace are contained. The keep out area applies to all layers of the host board. The recommended dimensions
of the host PCB keep out area are shown in Figure 4 (dimensions are in mm).
