The NanoUWB planar monopole antenna from Laird Connectivity adds UWB to consumer and IoT devices that need precise location data.

Laird Connectivity’s NanoUWB series of ultra-wideband (UWB) antennas connects to the company’s Sera NX040 series of UWB modules.

UWB, a reborn technology, brings location data to consumer and IoT devices.

The NanoUWB series consists of two models, differing through their MHF4L or MHF1 connectors. The antennas cover frequencies from 5850 MHz to 8250 MHz. The 50 Ω planar monopole design on a PCB mounts on boards or other surfaces through an adhesive backing. Antenna gain falls between +1.5 dBi and +3.9 dBi with a VSWR less than 2.5:1. It operates over temperatures from -40°C to +85°C (-40°F to +185°F).

Combined, the antenna and Sera NX040 modules are FCC, EU, UKCA, ISED, RCM, MIC, KCC, Bluetooth SIG, and FiRa Consortium certified. The module uses Bluetooth Low Energy (BLE) technology to connect and configure the device before use, much as connected Wi-Fi home devices use BLE provisioning from a smartphone. The module can connect to a host microcontroller through AT commands and Python scripts over an I2C, UART, or USB connection. The module also adds GPIO, analog-to-digital converter (ADC), and pulse-width modulation (PWM) functions to a device.
