摘　　要：研究了两种基于PBG接地板和开槽接地板的新型微带天线在TM0工作模式下的特性.仿真结果表明,与普通的微带天线进行比较,PBG结构和槽孔的引入可以有效地抑制表面波,使谐振频率降低,频带有所展宽,改善了天线的前向辐射,从而减小了天线的尺寸,提高了天线的性能.The TM0-mode performances of two microstrip patch antennas with slotted and PBG ground plates were investigated. Simulation results showed that the slotted and PBG ground plate for the microstrip antenna can efficiently suppress the surface wave compared to the ordinary microstrip antenna, the resonant frequency is decreased, the impedance bandwidth is enhanced,and the front radiation is improved, so that the size of the antenna can be reduced and the performance of the antenna is enhanced.
