5. Antenna Information
5.1 Antenna Type
TYWE3SE uses an onboard PCB antenna.
5.2 Antenna Interference Reduction
To ensure 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 adverse impact on the antenna radiation performance, avoid copper or traces
along the antenna area on the PCB. The following describes three antenna placement
solutions:
1. Place the antenna outside the PCB frame.
2. Place the antenna along the PCB frame without copper nearby.
3. Place the antenna in a carved area on the PCB.
