摘要

本文提出了一种加载匹配电路的埋在特定空腔内的超宽带低轮廓天线。所提出的天线通过同轴直接馈电，以实现低轮廓的特性。设计的天线在VSWR <3时达到$4:1的$带宽$(f_{L} ^{-}}-f_{L})$，而未加载匹配电路的天线仅达到$2.5:1的$带宽$(1.6f_{L}-4f_{L})$。最大尺寸仅约$0.17\lambda_{lll}$，剖面高度仅$0.055\lambda_{lll}$，使得该天线适合机载平台的应用。特殊腔体的最大长度为$0.33\lambda_{1lw}$，轮廓高度与天线相同，倾角为15°。

Ultra-wideband Low-profile Antenna Loaded With Matching Circuit

Ultra-wideband low-profile antenna loaded with matching circuit is presented in this paper, which is buried in a specific cavity. The proposed antenna is fed through coaxial directly to achieve a low-profile characteristic. The designed antenna is proposed to achieves a $4:1$ bandwidth $(f_{L^{-}}-f_{L})$ with VSWR <3, while the antenna without loaded with matching circuit only reaches a $2.5:1$ bandwidth $(1.6f_{L}-4f_{L})$. The maximum size is only about $0.17\lambda_{lll}$, and the profile height is only $0.055\lambda_{lll}$, which makes the antenna suitable for the application of airborne platforms. The special cavity’s maximum length is $0.33\lambda_{1lw}$, the profile height is the same as the antenna, and the angle of inclination is 15°.
