5 Antenna information
5.1 Antenna type
The CBU may select the PCB or FPC antenna.
5.2 Antenna interference reduction
To ensure the optimal Wi-Fi performance when the Wi-Fi 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 within the antenna area on the PCB.
