Module antenna characteristics The passive performance of the antenna for this module shall meet the following requirements: Parameter Operating frequency range: 2.4GHz2.4835GHz S11 <-10dB Efficiency >40% The antenna drawing of the module is as follows: 5 / 14 Midea IoT It is necessary to pay attention to the following points when the module antenna is placed: 1. The module is recommended to be placed at the edge of the electronic control board, with the antenna facing outward, away from metal parts and high-frequency signal lines. 2. Routing under the PCB antenna is forbidden, and do clearance processing. Routing of high-speed signals around and below the module shall be avoided. If the module cannot be avoided during routing, it is recommended to strictly follow the high-frequency signal routing rules, and perform signal packaging processing on the high-speed signals. 3. During installation, the front of the antenna shall avoid the metal shell or parts, so as not to shield the signal. Plastic shelter is allowed, but any interference between any object and the antenna is prohibited. 6 / 14 Midea IoT 4. Product structure diagram 4.1. Interface schematics Figure 2.1.
