【摘要】 本文基于0.18um标准CMOS工艺设计了一种应用于太赫兹检波的在片天线。天线采用微带馈电,谐振频率为340GHz,电磁仿真峰值方向性和增益分别为5.00dBi和-0.13dBi,-10dB带宽为8.2GHz,对应2.4%的相对带宽。设计了开路短截线匹配电路以实现天线到检波管的共轭匹配,提高功率传输效率。设计了在片天线的版图,芯片尺寸为730um×750um,面积为0.55mm2。更多还原

【Abstract】 This paper presents a design of 340-GHz on-chip antenna in 0.18-um standard CMOS process for terahertz detecting applications.The on-chip patch antenna fed by microstrip transmission lines is designed by electromagnetic simulation.The simulated peak directivity and gain of the antenna are 5.00 dBi and-0.13 dBi respectively.The-10 dB bandwidth of the antenna is8.2 GHz,which corresponds to 2.4% relative bandwidth.To improve power transfer efficiency,a short-stub matching network is inserted between the antenna and the detector.The layout of the patch antenna is designed.The chip occupies a core area of0.55-mm2(730×750 um2).更多还原
