摘要
为满足双频双方向的工作要求,文章设计了一款双频层叠H型缝隙微带阵列天线。采用基板—空气—基板3层结构及同相并馈功分网络馈电结构,在减小尺寸的同时实现阻抗的更优匹配。采用H型缝隙结构、错位双阵列八阵元结构实现双频双方向辐射特性。仿真结果显示,天线在2.8GHz和3.9GHz两个工作频段增益为12.4dB。中心频率为3.9GHz时,|S11|<-10dB,带宽为130MHz。中心频率为2.8GHz时,|S11|<-10dB,带宽为100MHz。
In order to meet the dual-frequency and dual-direction work requirements, a dual-band stacked H-slot microstrip array antennais designed. The substrate-air-substrate 3-layer structure and the in-phase and feed-fed network feed structure are used to achieve bettermatching of impedance while reducing the size. Dual-frequency bidirectional radiation characteristics are realized by H-type slot structureand misaligned dual-array eight-element structure. The simulation results show that the antenna has a gain of 12.4 dB in the two operatingbands of 2.8 GHz and 3.9 GHz. At a center frequency of 3.9 GHz,|S11|<-10 dB with a bandwidth of 130 MHz. At a center frequency of 2.8 GHz,|S11|<-10 dB with a bandwidth of 100 MHz.
