MULTIBAND ANTENNA SYSTEM WITH SHIELD
First Claim
1. An antenna system installed onto a circuit board of a mobile device, the system comprising:
- a planar dielectric substrate;
an upper conductor formed on an upper surface of the dielectric substrate and shaped as a coplanar wave guide, wherein the upper conductor includes a first ground part and a second ground part and a radiator formed between the first ground part and the second ground part;
a lower conductor formed on a lower surface of the dielectric substrate and shaped as a coplanar wave guide, wherein the lower conductor includes a third ground part and a fourth ground part and a electrode part formed between the third ground part and the fourth ground part;
via-holes passing through the planar dielectric substrate, where the via-holes electrically connecting the first ground part to the third ground part, the second ground part to the fourth ground part, and the radiator to the electrode part; and
solder balls for connecting the electrode part to an electric wire of the circuit board and the third ground part and the fourth ground part to ground of the circuit board.
