摘要

提出了一种双频l带近馈槽加载矩形微带贴片天线，并对其进行了理论研究和IE3D仿真。给出了输入阻抗、驻波比和回波损耗的数值计算结果，并与仿真结果进行了比较。分析了不同高度h2、槽宽和带钢宽度的影响，得到了双波段运行的最佳值。所得天线谐振频率分别为3.26GHz和6.20 GHz。频率比为1.95。仿真结果表明，该天线的下谐振频率带宽为1.63%，上谐振频率带宽为1.18%，理论带宽为3.35%，理论带宽为2.5%。

Analysis of L-strip feed slot loaded dual band microstrip patch antenna

A dual band L-strip proximity fed slot loaded rectangular microstrip patch antenna is proposed and investigated theoretically as well as simulated by IE3D. Numerical results for the input impedance, VSWR and return loss are presented and compared with simulated results. The effect on varying height h2, slot width and width of the strip are analyzed to obtained the optimum values for dual band operation. The resonance frequency of proposed antenna is found to be 3.26GHz and 6.20 GHz for lower and upper resonance frequency. The frequency ratio is found to be 1.95. The bandwidth of the proposed antenna is found to be 1.63% and 1.18 % (simulated) and 3.35 % and 2.5 % (theoretical) for lower and upper resonance frequency respectively.
