High-efficiency tiny bluetooth antenna with no clearance

05 Mar 2020 News

FRACTUS ANTENNAS has published a new application note to show how the DUO mXTEND™ antenna booster enables high-efficiency Bluetooth connection: DUO mXTEND™: Miniature and high-efficiency Bluetooth antenna“.

Small devices as smartwatches or smart meters have a lack of space, therefore, DUO mXTEND™ (NN03-320) is a tiny chip component ideal to be embedded into any small printed circuit board. This antenna booster, as it is only 7.0 mm x 3.0 mm x 2.0 mm and even more, it does not need any clearance beyond its footprint, like other traditional Bluetooth antennas.

This antenna booster has been designed for providing a top-quality Bluetooth operation, regardless of the antenna position on the device, either if the mounting of the component is at a corner of the PCB or just at the centre edge of the printed circuit board.

With more than a 70% average efficiency this miniature antenna allows the designer to reduce the size of the PCB as much as possible without losing performance, and the zero clearance beyond the antenna area leaves extra space to embed other elements nearby.



Barcelona-based Fractus Antennas SL designs, manufactures and commercializes miniature, off-the-shelf antennas for IoT, mobile connectivity, and short-range wireless devices. Founded as an independent antenna product business in 2015, Fractus Antennas was born out of the main Fractus operation and combines a respected R&D team with proven manufacturing capabilities and scale to bring to market a new generation of antenna products to meet the mobile and wireless connectivity needs of OEMs.
