| 摘 要： | 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。本文设计了一种机栽环形缝隙天线，实现了天线小型化和机载共形。该天线结构简单，满足VSWR〈1．4的频带宽为350～376MHz，满足VSWR〈2的频带宽为338-438MHz，且工作频率范围内的最大增益达到4．2dB。

| 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 micmstrip antertna can not meet the above requirements. Under the background of the airborne antenna miniaturization and conformal demand, this article de- signs a kind of airborne circular slot ar tenna. The structure of the antenna is simple, which meets pattern VSWR 〈 1.4 bandwi＆h of 350-376 MHz and meets pattern VSWR 〈 2 bandwidth of 338-438 MHz . Its maximum gain within the operating frequency range can be 4.2 dB. |
