Antenna types supported by the module
The module is equipped with PCB on-board antenna, and there is no other antenna
access mode.
In order to ensure the optimal WiFi or ble performance of the module, a certain empty area
shall be maintained in the antenna area of the module, and there shall be no components,
fixing screws or grounding layers in the accessories within the length of the antenna.
The direction of the antenna should be consistent with the discovery of the final product,
so that the antenna has the maximum radiation in the required direction.
The antenna cannot be completely covered by metal or metal shell, which will reduce the
energy radiated by the screen antenna and weaken the received energy.
There should be no ground plane for the positive transmission of the antenna.
As shown in the figure below, the left and right sides of the antenna shall be kept at least
6mm away from the ground plane.
