APPLICATION NOTES Navigate globally with RUN mXTENDTM - Antenna Component: RUN mXTENDTM FR01-S4-224 - Dimensions: 12.0 mm x 3.0 mm x 2.4 mm - Frequency regions: 1561 MHz, 1575 MHz, and 1598 MHz to 1606 MHz With more than 80% of efficiency, the new RUN mXTENDTM chip antenna component covers the frequency ranges used for operating at the global navigation systems: GPS, GLONASS and BeiDou. This new reference design illustrates a full satellite navigation performance, tested in two different evaluation board sizes, that allows location signal usability anywhere in the world. The miniature size (12.0mm x 3.0mm x 2.4 mm) and the high level of flexibility of the standard component makes this solution one of the best options for any application to be developed where global navigation systems are involved. The RUN mXTENDTM provides operation in three frequency regions: 1561 MHz (BeiDou E1 band), 1575 MHz (GPS L1 band) and from 1598 MHz to 1606 MHz (GLONASS L1 band). The RUN mXTENDTM chip antenna component and other Fractus Antennas products based on its proprietary Virtual AntennaTM technology are protected by one or more of the following Fractus Antennas patents.

PRODUCT DESCRIPTION FR01-S4-224 The RUN mXTENDTM Antenna Booster has been specifically designed for providing multiband performance in wireless devices enabling worldwide coverage. It is a multipurpose antenna solution capable of being adapted, with a high level of flexibility, to the antenna designer needs. The same antenna part can be used to cover different frequency ranges, since it offers the antenna designer the flexibility of selecting the frequency regions to operate through just the customization of the matching network. In particular, this application note illustrates how to use it for operating the global navigation systems: GPS, GLONASS and BeiDou. TOP BOTTOM Material: The RUN mXTENDTM Antenna Booster is built on glass epoxy substrate.

MATCHING NETWORK The specs of a Fractus Antennas standard product are measured in their evaluation board, which is an ideal case. In a real design, components nearby the antenna, LCD's, batteries, covers, connectors, etc. affect the antenna performance. This is the reason why it is highly recommended placing pads compatible with 0402 and 0603 SMD components for a matching network as close as possible to the feeding point. Do it in the ground plane area, not in the clearance area. This provides a degree of freedom to tune the RUN mXTENDTM Antenna Booster once the design is finished and taking into account all elements of the system (batteries, displays, covers, etc.). Please notice that different devices with different ground planes and different components nearby the RUN mXTENDTM Antenna Booster may need a different matching network. To ensure optimal results, the use of high Q and tight tolerance components is highly recommended (Murata components).
