本文提供了一种在不损失天线性能的情况下降低贴片阵列天线雷达散射截面的吸波方法。该方法基于使用导电聚合物的电磁带隙吸收体。首先，设计了中心频率为3.0 GHz的贴片阵列天线。然后，还设计了在X波段具有吸波性能的电磁带隙（EBG）图案。其次，使用玻璃纤维增强复合材料和导电聚合物制作了所设计的低雷达散射截面（RCS）贴片阵列天线。最后，对制作的天线的性能和雷达散射截面进行了测量，以确认吸波效率，并证明低雷达散射截面贴片阵列天线在X波段的可行性。
This paper provides a radar absorbing method to reduce the radar cross section of the patch array antennas without any loss of antenna performances. The method was based upon the electromagnetic bandgap absorber using a conducting polymer. First, the patch array antenna with a central frequency of 3.0 GHz was designed. Then, the EBG patterns were also designed that had a radar absorbing performance within the X-band. Second, the designed low RCS patch array antenna was fabricated using glass fiber-reinforced composites and conducting polymer. Finally, the antenna performances and the RCS of the fabricated antenna were measured in order to confirm the radar absorbing efficiency and to show the feasibility of the low RCS patch array antenna in the X-band.
