That's one slim cellular antenna! At about 220mm long from tip to tip and with a cable thickness of just 0.8mm, this 2.4GHz WiFi or BLE antenna is slim, compact, and sensitive, with a 4dBi gain. The antenna is the trace on the PCB that is at the end of the skinny coaxial cable. It has an adhesive sticker back, so you attach it to an enclosure.
It has a tiny MHF3/ IPEX3 / wFL / w.FL connector on the end - not a uFL connector! If you need a 2.4GHz antenna with uFL which is larger, check out this product.
Jargon buster
Plain-language definitions for the technical terms used above.
- 2.4GHz WiFi
- 2.4GHz WiFi is the common wireless network band used by many routers and embedded devices. It matters here because the module can use WiFi for firmware updates, separate from its Bluetooth serial function.
- BLE
- BLE stands for Bluetooth Low Energy, a Bluetooth mode designed for lower power use and modern phone compatibility. It matters because BLE support can make the module easier to use with Apple devices and battery-powered projects, though it may behave differently from classic serial Bluetooth.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
- w.FL
- A very small radio-frequency antenna connector used on compact wireless boards. It matters because you need a matching w.FL antenna or adapter before the board can use an external antenna.
