Conical Terahertz DRA (dielectric resonator antenna) have been designed and investigated at terahertz spectrum i.e. 10 THz. Lower terahertz frequency band is useful for high data speed communication and upper band is used for optical sensors and free space wireless communications. Novelty in this work is to open up research in. terahertz. A unique geometry based dual band terahertz DRA with mathematical formulations has been proposed. The comprehensive analysis in terahertz regime have been worked out with S11, VSWR, radiation pattern and efficiency using conical TDRA. The conical terahertz DRA is designed at 10 THz frequency with 4.9 dBi, gain with bore sight radiation pattern. The equivalent circuit of conical terahertz DRA have been evaluated for dynamic impedance showing frequency dependence nature.

圆锥形介质谐振器天线，用于太赫兹应用

锥形太赫兹DRA（介质谐振器天线）已经设计并在太赫兹频谱（即10 THz）下进行了研究。较低的太赫兹频段可用于高速数据通信，而较高的频段可用于光学传感器和自由空间无线通信。这项工作的新颖性在于开拓太赫兹研究。已经提出了具有数学公式的基于独特几何学的双频带太赫兹DRA。使用圆锥形TDRA对S11，VSWR，辐射方向图和效率进行了太赫兹状态下的综合分析。圆锥形太赫兹DRA设计为10 THz频率，4.9 dBi，具有视孔辐射方向图的增益。已经对锥形太赫兹DRA的等效电路的动态阻抗进行了评估，显示出频率依赖性。
