2.2. EVALUATION BOARDS 1 PORT (698-960 MHz and 1710-2690 MHz)
This Evaluation Board (part number: EB_FR01-S4-220-1B-2R-1P) integrates one ALL
mXTENDTM chip antenna component to provide operation in two frequency regions, from 698
MHz to 960 MHz and from 1710 MHz to 2690 MHz. A UFL cable connects this single
input/output port to the SMA connector.

2.2.1. 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 ALL mXTENDTM chip antenna
component 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 ALL mXTENDTM chip antenna component may need a different matching network.
To ensure optimal results, the use of high Q and tight tolerance components is highly
recommended (Murata components).
