Abstract:
1. An antenna device for a RF communication equipment, comprising a substrate comprising front and back sides, a planar antenna element and a group of at least one component connected to said antenna element, characterised in that said planar antenna element is fixed to said substrate back side, in that said group of at least one component is fixed to said substrate front side, in an area located under said antenna element, and connected to said antenna element through at least a first connecting means passing through said substrate, and in that it comprises a low resistivity layer buried into said substrate for connecting to ground to isolate at least said group of component(s) from electromagnetic disturbances induced by said antenna element, wherein said antenna element is a slot antenna element comprising at least one slot and having first and second terminals respectively connected to said group of at least one component and to said buried layer through said first connecting means and a second connecting means passing through said substrate.
