1. ANTENNA DESCRIPTION

The Dual-band Reach XtendTM 802.11 a/b/g/n WLAN Chip Antenna is engineered to operate at

both 2.4 GHz and 5 GHz bands.

Dual-band Reach XtendTM lets you achieve high performance at a low cost. Taking advantage

of both spatial and polarization diversity, it will increase the reliability of your device’s data rate.

This, combined with high isolation, makes it ideal for use within indoor (highly scattered)

environments while navigating through inconsistent hotspot infrastructures.

Other PCB form factors and configurations may require a different feeding configuration,

antenna in your design, please contact info@fractusantennas.com.

5. MATCHING NETWORK

The specs of a Fractus Antennas standard antenna 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 PI matching

network as close as possible to the antenna feeding point. Do it in the ground plane area, not in

the clearance area. This is a degree of freedom to tune the antenna once the design is finished

and taking into account all elements of the system (batteries, displays, covers, etc.).

6. ASSEMBLY PROCESS

Figure 6 shows the back and front view of the Dual-band Reach XtendTM chip antenna, and

indicates the location of the feeding point and the mounting pads:

Figure 6 – Pads of the Fractus Dual-band Reach XtendTM chip antenna.

As a surface mount device (SMD), this antenna is compatible with industry standard soldering

processes. The basic assembly procedure for this antenna is as follows:

1. Apply a solder paste to the pads of the PCB. Place the antenna on the board.

2. Perform a reflow process according to the temperature profile detailed in Table 3, Figure 8

on page 12.

3. After soldering the antenna 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 to or larger than 127 microns (5 mils) is

required.

Mounting Pads (2, 3 ,4): solder the antenna mounting pads to the

soldering pads on the PCB. These pads must NOT be grounded.

Feed Pad (1): the white circle on the top of the antenna indicates the position of the feed pad

in the bottom. Align the feed point with the feeding line on the PCB. See Figure 1.
