【摘要】 本文提出了一种新型的应用于室内分布天线系统的垂直极化全向宽带缝隙天线。该天线由一个变形的印刷单极子和一个开有多边形缝隙的地板组成。由于采用了缝隙辐射结构,天线在0.65到2.9GHz频带范围内电压驻波比(VSWR)小于1.5,相对阻抗带宽达到127%,基本覆盖了所有的2G、3G和4G-LTE室内通信频段。天线H面在整个工作频段内具有全向辐射特性,实测结果与仿真结果吻合较好。紧凑的结构使得该天线在室内分布天线系统中具极其良好的实用价值。更多还原

【Abstract】 A novel vertical polarized omnidirectional broadband slot antenna for indoor distribution antenna systems is presented.The proposed antenna consists of a deformed printed monopole on one side of the substrate and a polygon slot in the ground plane on the other side.Due to the utilization of the wideband slot structure,an impedance bandwidth of about 127%(0.65～2.9 GHz) for VSWR≤1.5 is achieved,covering all frequency bands for 2 G,3 G and 4 G communications.The proposed antenna has omnidirectional radiation pattern in its H-plane over the operating bands.The measured results agree well with the simulated ones.Compact structure makes the proposed antenna a perfect candidate for indoor distributed antenna applications.更多还原
