【摘要】 本文提出了一种在Ka波段工作的垂直折叠开槽圆形贴片天线。得益于圆形贴片中心的垂直折叠结构,天线实现了26.2 GHz～33.7 GHz的工作带宽,相对带宽达到了25%,在|S₁₁|<～10 dB的带宽范围内可以实现的最大增益约为7.9 dBi,并且在工作频带的大部分范围内增益均大于0 dBi,在较宽的频带范围内实现了良好的天线辐射性能。更多还原

【Abstract】 In this paper,a vertically folded circular patch antenna working in Ka-band is proposed.benefit by the vertical folding structure in the center of the circular patch,the antenna achieves a working bandwidth of 26.2 GHz～33.7 GHz,with a relative bandwidth of 25%.The maximum gain in the bandwidth range of | S₁₁| <-10 dB is about 7.9 dBi,and the gain is greater than 0 dBi in most of the working frequency band,thus achieving good antenna radiation performance in a wider frequency band.更多还原
