1.2.3. On-board Chip Antenna
The CH232BGN supports a built-in antenna option. When the customer chooses to utilize a built-
in antenna, the customer circuit board must comply with the following rules:
The antenna may not be located in the (6X8MM) red region, see Figure 3 below.
The antenna must located away from any metal or any components taller than 10MM;
The antenna cannot be shielded by any meal enclosure. Any cover or enclosure must be at
least 10MM from the antenna.
Figure 3: CH232BGN Circuit Board
We recommend that the CH232BGN module be placed in a corner of the user
’s circuit board.
This location provides optimal placement for antenna efficiency and helps to isolate the module
from other circuits.
