摘　　要：设计了一种新型基于哑铃型光子带隙(PBG)的宽带高增益E形贴片天线。实现X波段天线单元38.2%的阻抗带宽(VSWR<2)且频带内增益提高1-2.5 dB。将PBG结构应用于天线阵列,实现了全频带增益的提高,且单元端口互耦隔离度最大可提高5 dB。仿真和实测结果有好的一致性。This paper presents a new wide-band and high-gain E-shaped patch antenna based on dumbbell-shaped PBG structure.An impedance bandwidth of 38.2%（VSWR2）can be achieved for X-band E-shaped antenna and the gain can be improved by 1～2.5 dB in the bandwidth.Both of the gain and port isolation in the bandwidth can be improved by applying the PBG structure to E-shaped antenna array and the port isolation can be improved by 5 dB at most.Experimental results are in good agreement with simulation results.
