摘要

本文对两种类型的缝隙天线进行了设计、制作和测量。在2.4 GHz和5 GHz(工业-科学-医疗(ISM)频段和Hiperlan2频段)微带馈电槽天线中,我们采用了多种技术方法来实现阻抗特性,控制谐振的工作频率,提高谐振处的阻抗带宽,并实现微带馈电槽天线尺寸的小型化。通过将辐射单元从矩形槽改为z形槽,在槽边缘增加4个对称调谐桩,将槽拆分为双槽来制作槽天线。得到的两个工作频段的阻抗带宽在2.4 GHz频段达到16.07%左右,在5 GHz频段达到20.59%左右。给出了双z型槽天线的模拟和实测辐射方向图。

A dual broadband dual slot antenna
In this paper, two types of the slot antenna were designed, fabricated, and measured. We used several technical methods to perform the impedance characteristics, control the operating frequency of resonances, enhance the impedance bandwidth at the resonances and miniaturize the size of the microstrip-fed slot antenna at the 2.4 GHz and 5 GHz (the industrial-scientific-medical (ISM) bands and the Hiperlan2) bands. The slot antenna was fabricated by changing the radiation element from the rectangular slot to the Z-like slot, adding four symmetrical tuning stubs at the slot edges, and splitting the slot into a double slot. The obtained impedance bandwidths for two operating bands can reach about 16.07 % for the 2.4 GHz band and 20.59 % for the 5 GHz band. The simulated and the measured radiation patterns of the double Z-like slot antenna were shown.
