Semiconductor package
There is provided a semiconductor package, and more particularly, a semiconductor package including an antenna embedded in an inner portion thereof. The semiconductor package includes: a semiconductor chip; a main antenna disposed to be adjacent to the semiconductor chip and electrically connected thereto; a sealing part sealing both of the semiconductor chip and the main antenna; and an auxiliary antenna formed on an outer surface of the sealing part and coupled to the main antenna.
1. A semiconductor package comprising:
a semiconductor chip;
a main antenna disposed to be adjacent to the semiconductor chip and electrically connected thereto;
a sealing part sealing both of the semiconductor chip and the main antenna; and
an auxiliary antenna formed on an outer surface of the sealing part and coupled to the main antenna,
wherein the sealing part includes a groove formed in an outer surface of the sealing part at a position corresponding to the position of the main antenna, and the auxiliary antenna is formed in an inner portion of the groove.
2. The semiconductor package of claim 1 , further comprising a substrate having the semiconductor chip and the main antenna disposed on one surface of the substrate and having external terminals formed on the other surface of the substrate.
3. The semiconductor package of claim 1 , wherein the main antenna and the auxiliary antenna transmit and receive a high frequency in a millimeter band through the coupling.
4. The semiconductor package of claim 1 , wherein the semiconductor chip and the main antenna are electrically connected to each other by a bonding wire.
5. The semiconductor package of claim 1 , wherein the sealing part includes a protrusion part formed on an outer surface thereof at a position corresponding to that of the main antenna, and the auxiliary antenna is formed on the protrusion part.
6. The semiconductor package of claim 1 , wherein a thickness of the sealing part interposed between the main antenna and the auxiliary antenna is adjusted to thus adjust an antenna radiation pattern and an antenna gain.
7. The semiconductor package of claim 1 , further comprising a shielding film formed of a metal plating layer along a circumference of the auxiliary antenna on the outer surface of the sealing part.
8. The semiconductor package of claim 2 , wherein the main antenna is formed as a circuit pattern on one surface of the substrate.
