AccuraUWB FXUWB20.01 Ultra Wideband (UWB) Flex Antenna, 100mm 1.37mm SMA(M)

FXUWB20.01 Ultra-Wideband (UWB) Flex Antenna

The AccuraUWB FXUWB20 flexible polymer antenna, at 35*24.5*0.2mm, is a small form factor, ultra-thin, ultra-wideband (UWB) antenna with high efficiencies across the pulsed UWB communications operational bands. It adheres by a simple “peel and stick” process, attaching securely to non-metal surfaces via 3M adhesive. It enables designers to use only one antenna that covers all available UWB commercial bands, namely bands 1 through 15 simultaneously.

The AccuraUWB FXUWB20 antenna is a durable flexible polymer antenna that has a peak gain of 6dBi, an efficiency of more than 70% across the bands, and is designed to be mounted directly onto a plastic or glass cover. It is an ideal choice for any device maker that needs to keep manufacturing costs down over the lifetime of a product. It is ground plane independent and delivered with a cable and connector for easy connecting to the wireless module or customer PCB. Cables and connectors are customizable, however, the maximum micro coax cable length is 100mm. Like all such antennas, care should be taken to mount the antenna at least 10mm from metal components or surfaces, and ideally 20mm for best radiation efficiency.

Like all such antennas, care should be taken to mount the antenna at least 10mm from metal components or surfaces, and ideally 20mm for best radiation efficiency. Ultra-wideband (also known as UWB) is a low power digital wireless technology for transmitting large amounts of digital data over a wide spectrum of frequency bands typically spanning more than 500MHz with very low power for short distances. While the cable type and length are customizable, as is the connector, do note that a custom-designed antenna may be needed in those circumstances. Also tuning of the antenna may be needed in specific customer device environments. Taoglas offers this testing and tuning service subject to NRE and MOQ. Contact your regional Taoglas office for support.

The low power requirements of UWB mean increased battery life of sensors and tags leading to a reduction in overall operational costs. Taoglas has developed various innovative and new-to-market flexible embedded UWB antennas designed for seamless integration on plastics and using highly flexible micro-coaxial cable mounting while achieving high performance where space is limited. Taoglas UWB antennas have been designed for use with the recently launched Decawave ScenSor DW1000 module and are also compatible with any other UWB sensor modules on the market.


These short-pulsed antennas provide very fine range resolution and precision distance and positioning measurement capabilities. UWB signals enable inexpensive high definition radar antennas which find use in automotive sensors, smart airbags, and precision surveying applications amongst many others.

Home Network Connectivity

Smart home and entertainment systems can take advantage of high data rates for streaming high-quality audio and video contents in real-time for consumer electronics and computing within a home environment.

Position location & Tracking

UWB antennas also find use in Position Location and Tracking applications such as locating patients in case of critical condition, hikers injured in remote areas, tracking cars, and managing a variety of goods in a big shopping mall. UWB offers better noise immunity and better accuracy to within a few cm compared to current localization technologies such as Assisted GPS for Indoors, Wi-Fi and cellular which are at best able to offer meter level precision. Tethered Indoor positioning UWB systems that measure the angles of arrival of ultra-wideband (UWB) radio signals perform triangulation by using multiple sensors to communicate with a tag device.
