摘要:

设计了一种新型的微带印刷振子天线阵列.为了增加天线的带宽,使用一种新型的平面光子带隙(PBG)结构镶嵌在天线表面.通过优化PBG结构单元的尺寸,可以使电压驻波比(VSWR)小于1.5的频率带宽达到56.7%,而传统天线的带宽仅有36%.并且将一种新型的频率选择表面(FSS)作为天线的反射地板,降低了整个阵列天线的雷达散射截面.

Abstract:

A new printed dipole antenna array is given. In order to further increase bandwidth capabilities of this antenna, a novel low-cost smaller unit-cell planar photonic bandgap (PBG) structure is etched onto the antenna surface. By optimizing the sizes of the PBG structure, a bandwidth is of 56.7% is obtained where the voltage standing wave ratio (VSWR) is less than 1.5 while a bandwidth of 36% is obtained from the traditional structure. Moreover, a new Frequency Selective Surface (FSS) is used for the ground of the array antenna, which can reduce the radar cross section(RCS) of the antenna array.
