5 Antenna Information
5.1 Antenna Type
WB2L uses an onboard PCB antenna or external antenna with an I-PEX connector.
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.
For details about the onboard PCB antenna area on WB2L, see Figure 6-1.
