摘要

提出了一种基于台积电0.18μm标准CMOS技术的太赫兹直接探测器484GHz片上天线设计方案。采用Ansoft HFSS软件对微带传输线馈电的片上贴片天线进行了设计和仿真。为了提高功率传输效率，在天线和探测器之间插入了一个开根匹配网络。天线的峰值增益为3dbi，天线的带宽为85GHz，对应于28%的相对带宽。芯片的尺寸为1200μm×1000μm，贴片天线的面积为397μm×264μm。

The design and matching of THz on-chip antenna in CMOS

This paper presents a design of 484GHz on-chip antenna for THz direct detector in TSMC 0.18μm standard CMOS technology. The on-chip patch antenna fed by microstrip transmission lines is designed and simulated by Ansoft HFSS. To improve the power transfer efficiency, an open-stub matching network is inserted between the antenna and the detector. The peak gain of the antenna is 3 dBi, The bandwidth of the antenna is 85GHz, which corresponds to 28% relative bandwidth. The size of the chip is 1200μm×1000μm and the area of the patch antenna is 397μm×264μm.
