摘　　要：采用了圆环形结构和加载电阻的方法来提高微带贴片的带宽,对圆环形贴片天线的内场进行了理论分析,利用仿真与实测结果,分析采用电阻加载的方法对于天线带宽的影响。该天线的工作频段覆盖了2.2～2.6 GHz,其带宽达到了16.7%,缩减天线面积达到64%,而且做到了多频段工作。给出了HFSS的设计步骤,优化过程,结合模型仿真结果与实物的实测结果的对比,也证明了HFSS天线设计的高效和准确性。The circular structure and load resistance methods increases the bandwidth of the microstrip patch,the circular of the patch antennas vacant lot line is analysised. Throngh the simulation and test results,analysis of the resistance loading method for the bandwidth of the antenna effect of the an- tenna working band covers 2.2 - 2.6 GHz,its bandwidth is achieved 16.7% ,cut 64% of the antenna,and completes the multiple frequency work. The HFSS design steps ,optimization process is described. Combined with the simulation results and the measured results of physical contrast ,the HFSS antenna desian has high efficiency and accuracy.
