Tiny BLE 5 Modules with Integrated PCB Antenna Option


By moving the antenna to the PCB, manufacturers can now implement the u-blox’s NINA-B3 series of Bluetooth low energy modules into even smaller form factors.

u-blox announced that its popular NINA-B3 series of stand-alone Bluetooth 5 low energy modules now includes the NINA-B306/316 modules with integrated PCB antenna. The trapezoidal printed antenna, technology licensed from Proant AB, is said to enable superior performance and reception of data in a small form factor.

The NINA-B306/316 modules, with their fully integrated PCB antenna and global certification, makes implementing the BLE technology even easier, according to u-blox.


As noted in the announcement, BLE is rapidly becoming the short-range wireless technology of choice for a broad range of IoT applications, thanks to its security and robustness, coupled with higher data rates, longer range, support for mesh networking and exceptionally low power demands.

“The introduction of Bluetooth 5 makes the technology even more applicable to a range of IoT applications,” said Pelle Svensson, Market Development Manager, Product Center Short Range Radio at u‑blox.

BLE 5 Modules offer easier implementation

The NINA-B306/316 modules are fully pin- and software compatible with the entire NINA series, giving manufacturers a seamless upgrade path as well as design options.

Depending on the end application it may be more appropriate to use an external antenna, while for many a PCB antenna will offer technical and commercial benefits.

With its small form factor measuring 10x15x2.2 mm, the NINA-B306/316 modules offer users greater design freedom.
