Abstract :
In recent years a lot of research has been performed in the field of antenna integration. Very interesting is the integration of a planar radiating element in the package surrounding a chip. The electromagnetic field at the back of the antenna is not negligible, and may cause interference with the circuits in the chip, possibly encumbering the operation of the system. This interference was quantified by a numerical near field analysis, and shielding methods to reduce it were investigated.
