摘要
本文提出一种利用天线单元之间互耦来增加带宽的交织螺旋天线,采用在单元之间添加寄生枝节的方法提高单元之间的耦合,以此来削弱平面地板对天线的影响,实现了增加带宽的效果。仿真结果表明:通过这种方法可以实现天线的超宽带,未添加寄生枝节时,天线在5GHz-12GHz和18GH-30GHz频率范围内VSWR<2;在天线单元之间添加寄生枝节后,天线在5GHz-30GHz(6:1)频率范围内VSWR<2。
In this paper, a new tightly coupled Interwoven Spiral Array with the coupling between antenna elements to increase the bandwidth of the antenna is proposed. Improving the coupling to increasing bandwidth by adding parasitic branch between the cells which weak the influence of the ground. The simulated results show that the using of mutual coupling by this method increase bandwidth of antenna array effectively. Without the parasitic branch, the antenna is in the range of 5GHz-12 GHz and 18GH-30 GHz with VSWR <2,With the parasitic branch the antenna is in the range of 5GHz-30GHz(6:1)with VSWR <2.
