| 摘 要： | 提出了一种工作在太赫兹频段的双频缝隙贴片天线。在天线辐射贴片上加载“C”、“E”型辐射缝隙,改变天线表面电流的路径来实现双频特性。通过HFSS 15.0仿真软件对天线模型进行仿真,天线可以同时在300 GHz(291～306 GHz)和640 GHz(632～656 GHz)的频段下工作,最大增益达到了7.38 dB和10.50 dB。该双频天线结构简单,各项性能指标稳定,对于工作在太赫兹频段上的通信系统和无线传输系统具有一定的应用价值。

| Abstract: | A dual-frequency slot patch antenna in the terahertz region is presented. Loaded with C-and E-type radiation slots on the patch,the current path on the patch surface was modified to realize the dual-band characteristic. The simulation based on HFSS 15.0 modeling shows that the antenna can simultaneously operate well at two bands,namely 300 GHz (291~306 GHz) and 640 GHz (632~656 GHz). The corresponding maximum gains are 7.38 dB and 10.50 dB,respectively. The dual-band antenna has the characteristics of simple structure and stable performance,and it has the application value for terahertz communications and wireless transmission systems. |
