摘　　要：本文设计了1款由加载上层寄生贴片和加载圆环及扇形构成的宽波束双线极化微带天线单元以及1×8的天线阵列。通过加载上层寄生贴片以及寄生圆环与寄生扇形使得阻抗带宽与波束宽度得到有效展宽。所设计天线的阻抗带宽(S11<10dB)为6.47~7.01GHz,相对带宽为7.5%。天线辐射方向图在E面的半功率波束宽度达到150°,交叉极化比达到19dB、26dB,天线阵列主波束的最大扫描范围为-57°~56°。This article introduces a wide-beam dual-line polarization microstrip antenna composed of loading upper parasitic patch,loading ring and sector.By loading the upper layer parasitic patch,the impedance bandwidth is significantly broadened,and loading the parasitic ring and parasitic allows the beam to be effectively broadened.The impedance bandwidth(S11<10dB)of the designed antenna is 6.47~7.01GHz,and the relative bandwidth is 7.5%.The half-power beam width of the antenna radiation pattern on the E plane reaches 150°,and the cross-polarization ratio reaches 19dB and 26dB,the maximum scanning range of the main beam of the antenna array is-57°~56°.
