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).

5. ASSEMBLY PROCESS

Figure 6 shows the back and front views of the ALL mXTENDTM chip antenna component FR01-

S4-220. Due to the product configuration, the feeding pad can only be the pad 1.

Figure 6 – Pads of the ALL mXTENDTM chip antenna component FR01-S4-220.

As a surface mount device (SMD), the ALL mXTENDTM chip antenna component is compatible

with industry standard soldering processes. The basic assembly procedure for the ALL

mXTENDTM chip antenna component is as follows:

1. Apply a solder paste on the pads of the PCB. Place the ALL mXTENDTM chip antenna

component on the board.

2. Perform a reflow process according to the temperature profile detailed in Table 4, Figure 8.

3. After soldering the ALL mXTENDTM chip antenna component to the circuit board, perform a

cleaning process to remove any residual flux. Fractus Antennas recommends conducting a

visual inspection after the cleaning process to verify that all reflux has been removed.

The drawing below shows the soldering details obtained after a correct assembly process:

Figure 7 – Soldering Details.

NOTE(*): Solder paste thickness after the assembly process will depend on the thickness of the

soldering stencil mask. A stencil thickness equal or larger than 127 microns (5 mils) is

required.
