To a lesser extent, PCB copper thickness (T) and proximity of same layer

r

 of 4.6 at 1.5 GHz) and different PCB thickness. One ounce copper is assumed for 

the thickness of the top layer. If a Multi layer PCB is used, the thickness is the 
distance from signal track to nearest ground plane.

Topology

It is recommended that the antenna connection PCB track be routed around the 
outside of the module outline, kept on a single layer and have no bends greater than 
45 degrees. It is not recommended, for production reasons, to route the track under 
the module.
