摘要
介绍了一种用于超宽带通信的平面型的小型天线。该天线采用相对介电常数为2．65的微带电路制作，天线尺寸为3．8cm×2．8cm。天线输入阻抗50n，在～10 GHz之间的驻波系数小于2。首先介绍了各种用于超宽带通信的平面型天线，讨论了镜像Bow-ti微带电路天线设计过程。最后用数字仿真软件对该天线进行了优化设计，并分析了天线的频域和时域特性，结果表明该天线能够满足超宽带通信的要求。
A small planar antenna for UWB communication was presented, which was made in double- side printed circuit board （PCB） of size 3.8 cm × 2.8 cm, using RF4 substrate of relative dielectric permittivity 2.65. The input impedance of the antenna was 50 Ω, and a VSWR of lower than 2 in the frequency range 3 GHz ～ 10 GHz. Varied planar antenna for UWB applications were reviewed, the design of mirror printed Bow-tie was discussed, then the performance of the antenna was analyzed in frequency domain and time domain, and optimized using CST and Ansoft Designer package. The results show that the antenna can be used in UWB communication.
