提出了一种利用三维基片集成圆波导（3D-SICW）实现的太赫兹滤波天线。滤波天线设计在低温共烧陶瓷基片上。与传统的平面结构不同，3D-SICW的功率方向是沿着Z轴方向
这将显著提高器件在THz频率下的性能。该滤波天线由两个3D-SICW谐振腔和一个标准基片集成波导（SIW）谐振腔构成，其中一个SICW谐振腔和标准基片集成波导谐振腔通过电耦合构成带通滤波器，另一个SICW谐振腔作为天线。结果表明，滤波天线的通带范围为170.4 ~ 177.8GHz，增益约为5.7dB。最后，对滤波天线进行了加工和测量，验证了仿真预测的正确性.在如此高的频率下，测量结果和模拟结果吻合得很好。
A new terahertz (THz) filtering antenna realised by 3D substrate integrated circular waveguide (3D-SICW) is presented. The filtering antenna is designed on a low-temperature co-fired ceramic substrate. Different from traditional planar structure, the direction of power in 3D-SICW is along Z
-axis and this will significantly enhance the performance of the devices at THz frequency. The filtering antenna is constructed by two 3D-SICW cavities and a standard substrate integrated waveguide (SIW) cavity, where one SICW cavity and the standard SIW cavity form the bandpass filter by using electric coupling and the other SICW cavity is used as antenna. The results indicate that the passband of filtering antenna range from 170.4 to 177.8 GHz and the gain of antenna is about 5.7 dB. Finally, the filtering antenna is fabricated and measured to verify the simulation prediction. The measured and simulated results are in good agreement at such high frequency.
