摘　　要：为了提高微带天线的阻抗带宽,该文提出并设计了一种L形探针馈电宽带微带天线。天线采用L形探针馈电方式补偿探针的感抗,并加载缝隙形成多调谐回路,展宽工作带宽,HFSS仿真结果表明该天线阻抗带宽(电压驻波比VSWR<2)66.9%,增益最大值9.35dBi。In order to improve the impedance bandwith of microstrip antenna,an L-shaped probe fed broadband microstrip antenna is proposed and designed.The antenna is fed by L-shaped probe to compensate the inductive reactance of the probe,and loading the slot to form a Multiple resonance circuit to expand the working bandwidth.HFSS simulation results show that impedance bandwidth of the antenna(VSWR<2)is 66.9%,the maximum Gain is 9.35 dBi.
