10 General Application Guidelines
11 Lead Free Soldering
The antenna has been tested and approved for lead free soldering. (See 12.4). Follow the guidelines and
reflow temperature vs time data for the solder paste supplied by the solder manufacturer.

Placement of the antenna.
The antenna shall be placed on an area with the PCB cut out (see drawing on page 7), preferably at the
edge of the PCB.
Placement of GPS radio module.
To avoid losses in the strip line, the module shall be placed as close to the antenna as possible.
Matching Circuit
The antenna requires a matching circuit, a PI network is recommended. This should be placed as close
to the antenna feed as possible.
Component values are depending on antenna placement, PCB dimensions and location of other
components.
Vias should connect all ground layers. Vias should be used to fence in the feed track from the radio to
the antenna. Vias should also be placed close to the ground pads of matching components. Vias size
and spacing depends on the application but generally 0.3 to 0.5mm diameter, spacing 3 to 10mm.
Strip line.
The strip line must be dimensioned according to your specific PCB. No crossing strip lines are allowed
between the strip line and its ground plane.
Via connections.
To avoid spurious effects, via connections must be made to analogue ground.
Clearance.
Minimum clearance to other components is 2-5 mm.
Casing material.
No metal casing or plastics using metal flakes shall be used, avoid also metallic based paint or laquer.
Note ! Incorrect implementation of the antenna will affect the performance.
