5 Antenna information
5.1 Antenna type
ZT3L only uses the onboard PCB antenna.
5.2 Antenna interference reduction
To ensure the optimal Wi-Fi 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.
