Dual-band GNSS/BT embedded antenna for IoT
Richardson RFPD, Inc., an Arrow Electronics company, has announced the availability and full design support capabilities for the DUO mXTEND™ dual-band embedded antenna from Fractus Antennas S.A.

The DUO mXTEND antenna booster is part of a new generation of antennas based on Fractus Antennas’ Virtual Antenna™ technology. This technology enables replacing conventional and custom antennas with a new class of antenna boosters, including miniature and off-the-shelf chip antenna components. These new multiband, multipurpose chip antennas fit in a variety of wireless platforms. This enables simpler, faster and less expensive designs versus custom versions.

The DUO mXTEND also incorporates a revolutionary design approach that eliminates the need for clearance area beyond its already-reduced footprint. The combination of these two miniaturizing features makes DUO mXTEND ideal for small and portable tracking devices, further eliminating the need for custom antenna development.

This miniature, high-efficiency antenna is versatile and can be optimized for a variety of requirements through external matching networks.

The DUO mXTEND is ideally suited for GPS/GALILEO/GLONASS/BeiDou modules, smart tracking devices, sport navigators, handsets and smartphones, tablets, digital cameras, and smartwatches and wearables.

Additional key features of the DUO mXTEND include a VSWR of under 2.5:1, temperature rating of  -40 to +125 ºC, impedance of 50 Ω, and dimensions of 7.0- x 3.0- x 2.0-mm. Average efficiency comes in at > 60% at 1561 MHz, > 70% at 1575 MHz, and > 60% at 1598-1606 MHz. Peak gain is 1.6 dBi at 1561 MHz, 1.8 dBi at 1575 MHz, and 1.1 dBi at 1598-1606 MHz.

Fractus Antennas offers a free design service that will test the DUO mXTEND in a given device. The NN Wireless Fast-Track service promises a 24-hour turnaround of a chip antenna design and custom matching network for the device.
