| 摘要: |
| 设计了一种基于0.18μm互补金属氧化物半导体（Complementary Metal Oxide Semiconductor, CMOS）工艺的94GHz频段宽带片上天线。该天线采用改进的单极子天线形式，以实现较宽的阻抗带宽。天线馈电形式采用共面集成波导（CPW）馈电结构，该结构便于毫米波天线探针台测试系统测试。此外，通过采用全波仿真软件HFSS，对天线衬底尺寸对天线阻抗和辐射性能的影响进行对比分析。所设计的天线工作频带（|S11|≤-10dB）为74~117.6GHz，94GHz频点处的增益为1.35dBi。该天线具有工作频带宽、辐射性能好等特性，可实现天线与IC芯片的一体化片上集成，满足宽带无线通信系统或毫米波雷达系统高集成度、小型化的应用需要。 |

| Abstract: |
| A 94GHz wideband on-chip antenna is designed based on 0.18μm CMOS technology. A modified monopole antenna is adopted in the design to achieve wide impedance band. In order to match the antenna test system, co-planar waveguide (CPW) is used as the feeding part. Furthermore, the influence of the substrate size on the impedance and radiation performance is analyzed by use of HFSS software. The designed antenna has an operating bandwidth from 74GHz to 117.6GHz and its gain is 1.35dBi at 94GHz. The designed antenna has wide bandwidth and good radiation performance to achieve the on-chip integration of antenna and IC chip for wireless communication and millimeter wave radar applications. |
