Classification: CPC H | IPC H

Claim 7:
8. A semiconductor device comprising:
an integrated circuit (IC) comprising a radio frequency (RF) circuit and an RF terminal configured to transmit or receive RF signals;
a substrate comprising an antenna proximate to a first side of the substrate facing away from the IC and comprising a conductive feature proximate to a second side of the substrate facing the IC, wherein the IC is attached to the second side of the substrate, and the RF terminal of the IC is electrically coupled to the conductive feature of the substrate, wherein there is no direct electrical connection between the RF terminal of the IC and the antenna, and the antenna is configured to be electromagnetically coupled to the RF terminal of the IC to transmit or receive the RF signals; and
a flexible circuit attached to the substrate, wherein the flexible circuit is configured to be bendable at an angle of ninety degrees, wherein the flexible circuit is electrically coupled to the IC and the substrate, wherein a first segment of the flexible circuit is disposed within lateral extents of the substrate, and a second segment of the flexible circuit is disposed outside the lateral extents of the substrate, the second segment of the flexible circuit comprising an electrical connector, wherein the antenna is disposed between the flexible circuit and the IC, wherein the first segment of the flexible circuit has an opening, wherein the antenna is exposed by the opening.
