Wireless modules based on radio frequency technology need to transmit and receive electromagnetic wave signals through antennas. Common types of antennas on the market include ceramic antennas, on-board antennas, rod antennas, and external antennas. External antennas are reserved for IPEX sockets on the PCB. There are many optional antenna types. This SKYLAB editor will take you to understand the UART interface WiFi module of the onboard antenna.
What is PCB Onboard Antenna
The on-board antenna directly uses the PCB as the medium, and the antenna is realized through the PCB process. It does not need to be assembled separately for testing and use, and it is not easy to touch and damage and easy to assemble. This PCB on-board antenna is widely used in WiFi modules, Bluetooth modules, ZigBee and other wireless modules that work in the 2.4GHz frequency band.

USB interface PCB onboard antenna WiFi module WG217 is a slave device 2.4/5GHz dual-frequency USB interface WiFi module developed by SKYLAB based on the RTL8811 solution, which complies with IEEE802.11b/g/n/ac wireless standards; all devices in the system are always in a passive waiting state for connection, and only the background server actively initiates a connection with the device and requests or uploads and downloads data. The maximum speed is 433Mbps. In 11b mode, the transmission power is +18dBm. In 11n mode, the transmission power is 15~16dBm. In 11ac mode, the transmission power is 9~11dBm. The transmission distance can reach 150M, which can be applied to devices that require high-speed WiFi transmission and have a USB interface.
It should be noted that these PCB on-board antenna WiFi modules also support the external antenna of the IPEX socket. When making WiFi module selection, customers can choose the antenna version according to actual needs. Compared with the PCB on-board antenna, the advantage of the IPEX socket external antenna is that there are more optional antenna types, and an external antenna with a large gain can be connected externally to improve the sensitivity of the received signal and meet the data transmission needs of a slightly longer distance.
