| Research Abstract |
On-chip antennas are demanded to further lower the cost of wireless CMOS ICs. The low resistivity of silicon substrates is a major obstacle to fabricate high-gain on-chip antennas. We placed an artificial dielectric layer (ADL) between an antenna and Si substrate to improve the antenna gain. A half-wave dipole-antenna that has ADL was designed and fabricated using a CMOS-compatible process with one poly-Si and two metal layers. Using the ADL enhanced gain by 3-dB. The measured gain was the highest ever achieved for the antennas operating at around 10 GHz on low-resistivity Si substrates. A method for further improvement is discussed. In addition to the improved antenna, we investigated wireless communication circuits monolithically integrated with antenna and nano-carbon materials for electromagnetic shielding applications.
