Multi-chip semiconductor package with integral shield and antenna
View Patent ↗A transceiver package includes a substrate having an upper surface. An electronic component is mounted to the upper surface of the substrate. A shield encloses the electronic component and shields the electronic component from radiation. The transceiver package further includes an antenna and a dielectric cap. The dielectric cap is interposed between the shield and the antenna, the shield being a ground plane for the antenna.
1. An electronic component package comprising:
a substrate comprising a first surface comprising a first central region defined by a first shield ring;
a first shield electrically coupled to said first shield ring, said first shield being continuous;
a first electronic component coupled to said first central region;
a second shield ring defining a second central region of said first surface of said substrate;
a second electronic component coupled to said second central region; and
a second shield enclosing said second electronic component, said second shield being electrically coupled to said second shield ring.
2. The electronic component package of claim 1 wherein said substrate further comprises:
a second surface; and
a ground shield extending from said first surface to said second surface.
3. The electronic component package of claim 2 wherein said ground shield comprises a plurality of electrically conductive ground vias.
4. The electronic component package of claim 3 wherein said ground vias are spaced sufficiently close to one another to prevent radiation from passing between said ground vias.
5. The electronic component package of claim 2 wherein said ground shield extends around a periphery of said substrate.
6. The electronic component package of claim 1 wherein said first shield ring comprises upper ground traces.
7. The electronic component package of claim 1 wherein said first shield comprises a shield connection surface, said electronic component package further comprising an electrically conductive adhesive coupling said shield connection surface to said first shield ring.
8. The electronic component package of claim 1 wherein said first shield comprises a shield connection surface, said first shield ring corresponding in shape to said shield connection surface.
9. The electronic component package of claim 8 wherein said shield connection surface comprises a rectangular annulus.
10. The electronic component package of claim 1 wherein said first electronic component is shielded from said second electronic component by said first shield and said second shield.
11. The electronic component package of claim 1 wherein said first shield is grounded separately from said second shield.
12. The electronic component package of claim 1 wherein said first shield and said second shield are commonly grounded.
13. The electronic component package of claim 12 wherein said first shield is electrically coupled to said second shield.
14. The electronic component package of claim 1 wherein said first shield ring and said second shield ring share a common side.
