Abstract
An antenna structure is fabricated on a chip. The antenna structure includes a shielding layer, a dielectric layer and an antenna layer. The shielding layer includes a plurality of mutually isolated regions. The entire structure may be fabricated using conventional CMOS processes.
Claims19
A single-chip integrated circuit comprising:
- a base portion including an integrated circuit;
- a substantially planar antenna;
- and,
- a shielding layer between the base portion and antenna effective to shield cross talk between the base portion and the antenna, said shielding layer characterized by a plurality of mutually isolated regions.
1 more element
