摘　　要：本文设计了一个新型小型化蝶形微带天线,该天线采用微带馈线,通过优化辐射贴片和在接地板开槽的方法,减小了天线尺寸,最终所实现的天线尺寸为32mm×32mm,与传统蝶形天线相比尺寸减小23%.测量结果表明:天线S11<-10dB的阻抗带宽能达到120 MHz(2.49GHz^2.61GHz).同时,天线最大增益为2.5dBi,可以应用于无线传输领域.A novel miniaturized bow-tie microstrip antenna is proposed In this paper.The antenna is fed by the microstrip line.In order to reduce the size of the antenna,the optimized bow-tie patch and the ground plane with rectangular window is employed.Finally,the dimensions of the proposed antenna are32mm×32mm.Compared with the traditional antenna,the antenna size is reduced by 23%.The measured results show that the impedance bandwidths for S11〈-10 dB reach up to 120 MHz（2.49~2.61GHz）.Meanwhile,the highest gain of the antenna is 2.5dBi.It can be used in the wireless communication.
