摘要

提出了一种用于超宽带应用的三维天线设计方案。天线的尺寸为58毫米× 58毫米× 76.5毫米，由两个相同的臂组成。每只手臂由一个中空的准半球和一个内管组成。仿真中采用50 Ω同轴电缆馈电天线，以评估电缆效应对天线性能的影响。仿真结果表明，该天线能够在7 ~ 32.5 GHz频段工作，S11低于-10 dB，同时保持全向辐射方向图。在整个阻抗带宽上，模拟总效率在88%以上，表明天线性能良好。实现增益随频率变化在0.8 ~ 3.1 dBi之间。

Design of a quasi-hemispherical UWB antenna

This paper proposes a design of three-dimensional antenna for ultrawideband applications. The antenna has dimensions of 58 mm × 58 mm × 76.5 mm and is composed of two identical arms. Each arm consists of a hollow quasi-hemisphere and an inner for it tube. In the simulation, a 50 Ω coaxial cable is employed to feed the antenna in order to assess the change of the antenna performance due to the cable effect. The simulated results show that the antenna is capable of operating in the frequency band from 7 to 32.5 GHz with S11 below -10 dB, while maintaining an omnidirectional radiation pattern. The simulated total efficiency is above 88 % over the entire impedance bandwidth which indicates a good antenna performance. The realized gain varies from 0.8 to 3.1 dBi with frequency.
