2.4GHz Flexible WiFi/BLE Antenna (U.FL)

This antenna is perfect for use together with our WiFi and/or BLE Challenger boards with a U.FL connection, or any other board/module with U.FL. It's a 42mm by 12mm flex PCB antenna with double-sided tape on the backside making it perfect for mounting inside of an enclosure. It has been designed specifically to be attached to a plastic wall of around 1.5-2.0mm thickness. In the open air, it does not perform as well as when it has been mounted properly. A great antenna for the Challenger RP2040 WiFi/BLE MkII U.FL board! Performance Return loss diagram of the antenna mounted on a 2mm thick 15cm x 10cm polycarbonate sheet:
