Bulid-in Antenna

The built-in antenna range covers internal radiators: adhesive FPC, PCB patch, copper helical spring, stamped metal, 13.56 MHz NFC, copper tube and laser-engraved LDS. Copper springs run 15-37 mm at 2 dBi on 433/470/650/868 MHz or 2.4 GHz, gold or nickel plated, and weld to the board. Stamped 2.4/5.8 GHz parts run 16.8-31.3 mm. NFC coils serve access control and mobile payment, with reverse ferrite and adhesive backing.

FPC and PCB versions connect through IPEX, U.FL or MHF on RF1.13 cable, with 3M adhesive, on 4G 698-2700 MHz, 2.4/5.8 GHz WiFi, 433 MHz, 88-108 MHz FM and 700-6000 MHz 5G. The LDS option covers 2.4/5.8 GHz WiFi, Bluetooth and 4G, with tuning and OTA testing. Matching can be checked in an anechoic chamber. A 0.6 mm FM FPC mounts with adhesive, and cable length can be customized.
