Fractus Antennas has launched a mobile antenna that enables coverage at 3G, 4G and 5G — the TRIO mXTEND chip antenna component. The TRIO mXTEND has been specifically designed to provide flexibility to operate any required frequency band inside any wireless device. It is capable of operating the main mobile communication standards, enabling worldwide coverage, as well as GNSS such as GPS, GLONASS and BeiDou (1561 MHz, 1575 MHz and 1598-1606 MHz) and the main short range wireless bands such as Bluetooth and Wi-Fi (2400-2500MHz and 4900-5875MHz) through the same antenna component. The TRIO mXTEND is a modular, multiband and multi-port antenna component that enables top-quality worldwide coverage at any mobile communication standard. Its reconfigurable and off-the-shelf nature allows multiple architectures so the antenna component can be assembled into any mobile or IoT device. It has been designed for providing mobile operation in three different frequency regions: 698-960 MHz, 1710-2690 MHz and 3400-3800 MHz. In addition, TRIO mXTEND is presented in an ultra slim component of 1 millimeter that enables easy placement into any device. The Fractus Antennas team will be at Mobile World Congress in Barcelona, either at the venue or in Fractus Antennas Headquarters, which is based in the city. Those interested are invited to arrange a meeting.
