机载共形的双环微带缝隙全向天线

机载共形的双环微带缝隙全向天线

内容简介：机载全向天线不但要满足水平面全向的指标要求，而且要与机体表面共形设计，常规的单极子天线和微带天线均无法满足要求。提出一种双环微带缝隙天线，可以实现机载共形的全向天线。分析了系统对机载天线的要求、双环微带缝隙天线的展宽带宽的方法，并给出了该天线的设计参数和实测结果，实测结果与仿真结果一致，验证了设计方法的正确性。

Abstract：The airborne omni-directional antenna must have the omni-directional performance in horizontal plane, and also have conformal shape with the surface of airplane. The common monopole antenna and microstrip antenna can not meet the above requirements. The paper presents the mierostrip dual-slot antenna in order to realize the airborne conformal omni-directional antenna. The requirements for the airborne antenna of system and the methods for microslrip dual - slot antenna to broaden the band are analyzed, and then the design parameters and the measurement results are given. The measurement results and the simulation results are consistent, which can validate the design methods.
