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.

需要片上天线来进一步降低无线 CMOS IC 的成本。硅衬底的低电阻率是制造高增益片上天线的主要障碍。我们在天线和硅基板之间放置了人工介电层 (ADL)，以提高天线增益。具有 ADL 的半波偶极子天线是使用 CMOS 兼容工艺设计和制造的，具有一层多晶硅和两层金属层。使用 ADL 将增益增强 3 dB。测得的增益是在低电阻率硅基板上工作在 10 GHz 左右的天线所实现的最高增益。讨论了进一步改进的方法。除了改进的天线之外，我们还研究了与天线和纳米碳材料单片集成的无线通信电路，用于电磁屏蔽应用。
