Abstract

This paper presents the design of a log spiral antenna operating at THz frequencies. The antenna was designed and simulated numerically by using the CST software within the frequency range 0.1–3.0 THz. It is found that the antenna is characterized with a wideband impedance matching which extends from 1.0 to 2.8 THz (|S11|< −10 dB)), high directivity with a maximum value Dmax = 5.61 dBi at 2.05 THz, high gain with a peak Gmax = 4.72 dBi at 2.2 THz, and high efficiency with a maximum ηmax = 81.5 % at 1.38 THz. With these obtained performances, we estimate that our proposed structure can be a good candidate for THz source applications.

光导源用宽带高指向性对数螺旋太赫兹天线的设计

本文介绍了一种工作在太赫兹频率下的对数螺旋天线的设计。利用CST软件在0.1 ~ 3.0 THz频率范围内对天线进行了设计和数值模拟。结果表明，该天线具有1.0 ~ 2.8 THz的宽带阻抗匹配(|S11|<−10 dB)， 2.05 THz时的高指向性，峰值Dmax = 5.61 dBi, 2.2 THz时的高增益，峰值Gmax = 4.72 dBi, 1.38 THz时的高效率，最大ηmax = 81.5%。根据这些获得的性能，我们估计我们提出的结构可以成为太赫兹源应用的良好候选。
