【摘要】 提出了一种超宽带叶片形单极天线,该天线在叶片形薄铜片上开三个孔和用相对介电常数为3.5的单层覆铜介质板作接地板。实验天线的实测结果从1.3GHz到29.7GHz约22∶1的超宽频带上,反射损耗都在-10dB以下。这种天线的频带覆盖了L、C、X、Ku各频段,应用前景十分广阔。更多还原

【Abstract】 A leaf-shaped monopole antenna with extremely wide bandwidth is introduced.The proposed antenna is composed of a leaf-shaped metal plate with three circular holes vertically mounted on a ground plate with a dielectric cladding of relative permittivity 3.5.The measured-10dB return loss bandwidth is from 1.3GHz to 29.7GHz with the ratio bandwidth of about 22:1.This ultra-broadband width covers L,C,X and Ku bands,which is suitable for extensive applications.更多还原
