Last updated on November 2016 (c) 2016 FRACTUS ANTENNAS, S.L. - 5 APPLICATION NOTES 2.3. 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 note 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).
