摘　　要：设计了一种新型单贴片单层的开缝微带天线。天线开缝后产生了两个相近的谐振点,通过对缝隙的调整,使得两个谐振点之间的S11<-10dB。带宽因此也得到了比较大的提高。仿真与实测结果表明,该新型天线工作于2.64GHz时,带宽达到了10%(S11<-10dB)。由于此种方法对天线的整体结构没有改变,并且只采用了传统的同轴馈电。因此制作成本低,结构简单,同时还保证了天线的低剖面性。A novel single-layer single-patch wideband circular microstrip antenna with slots is proposed. It can create multiple resonant frequencies by loading two L-shape slots, by adjusting the size of the slots. It makes these operating frequencies are generally close to each other, with the midband S11 under a resonant value（- 10dB for instance）,the resultant bandwidth can be winder. Both simulated and measured results show a impedance bandwidth（return loss〈-10dB） of 10% from 2.64GHz to 2.92GHz is obtained for this novel antenna. It＇s easy to make and the profile is low due to the effective method.
