Compared with the traditional microwave applicators, the exposed inner conductor of this applicator is replaced by a cone helical antenna with the reflect shade. 这种辐射器与常规微波辐射器不同的是,其前部的内导体被一个带有反射罩的锥形螺旋天线所替代。
This paper has made a theoretical analysis of active receiving antenna formed by combining negative impedance converting circuit with small cone helical antenna, and pointed out the stable working conditions for such an active antenna. 本文对用负阻抗变换电路同小圆锥螺旋天线相结合,构成的有源接收天线进行了理论分析,并给出了该有源天线稳定工作的条件。
Study on the Broadband Characteristics of Sphere and Cone Loaded Single-Pole Antenna 球形和锥形加载单极子天线的宽带特性研究
Their installation on a plane and conformal installation on a cylinder and the surface of a cone are researched, respectively. The influence of installation surface curvature on the bandwidth, axial ratio, radiated pattern, and S-parameter of antenna elements are analyzed detailedly. 2. 对两种天线单元在平面、圆柱面以及圆锥面共形安装时,安装表面曲率对天线单元工作频带宽度、轴比特性、方向图、S参数等的影响进行了详细分析。
