| 摘 要： | 针对现代无线通信设备多模、多频带工作、小型化的趋势,结合圆环微带天线频带宽和单板子微带天线结构简单等优点,设计了一种新型杯型单极子超宽带天线.通过打孔的方式改变辐射元的结构,使其同时具备圆环天线和单极子天线的优点,天线的性能因此大大得到改善.根据制作天线的实测结果表明,带孔杯型单极子天线在频率范围2.9～25.0 GHz内VSWR≤2,覆盖了从S至K波段.该天线覆盖频带宽、结构紧凑,适用于现代无线通信.

| Abstract: | The design of compact and multi-band antenna is increasingly important as multimode and multi-band small communication equipment develops.A novel ultra-wideband,cup-shaped monopole antenna with three holes is presented with the virtues of the ring microstrip and monopole antennae.Experimental results show that the antenna bandwidth is greatly improved when compared to a traditional monopole antenna.The antenna offers an ultra-broadband performance in the frequency band 2.9-25.0 GHz,covering the L to K bands... |
