DUO mXTEND™ & NANO mXTEND

UWB (NN03-320 & NN02-101)

Cover any Ultra-Wideband frequency with DUO mXTEND™ or

NANO mXTEND™

Ultra-Wideband (UWB) technology is utilized in a growing variety of IoT applications, including

smart locks, asset tracking systems, as well as precision agriculture and many more. At Ignion

we enable you to easily maximize the antenna performance in your next UWB product.

Ultra-wideband offers a precise indoor and outdoor location with positioning accuracy under 10

centimeters. Unlike Bluetooth, which estimates location based on signal strength, UWB

calculates the time it takes for the signal to travel back and forth, thus achieving a higher

level of accuracy. In security applications like passive keyless entry and automotive, building

automation, and smart homes, knowing the precise location or distance can be critical to the

application.

UWB is a spread spectrum technology that radiates very narrow pulses in the order of

nanoseconds, covering a wide bandwidth of frequency (typically between 3.1 GHz and 10.6

GHz). This reduces interference and enables high data rates, making it a reliable option for

applications such as real-time collision avoidance.

With an optimized antenna, UWB provides high accuracy, high energy efficiency, low radio

interference, and high data rates. Ignion DUO mXTEND

and NANO mXTEND

make it

easy to cover the whole UWB frequency spectrum (3.1 GHz - 10.6 GHz).

This application note shows how the Virtual Antenna® components can be used to operate in

the UWB frequency bands from 3.1 GHz up to 8.5 GHz.
