Antenna interference reduction

To ensure the optimal Zigbee performance when the Zigbee module uses an onboard

PCB antenna, it is recommended that the antenna be at least 15 mm away from other metal parts.

To prevent an adverse impact on the antenna radiation performance, avoid copper

or traces along the antenna area on the PCB.
