摘　　要：针对高速临近空间飞行器测控的需求,研制了一款质量轻、体积小、低剖面、加工简单、成本低、易与有源电路一起集成的宽带低剖面弹载嵌入式共形天线,通过天线罩实现与弹体的共形。天线采用印刷偶极子形式,通过与天线罩共形的金属结构壁进行耦合,有效地降低了天线的剖面高度。该天线的相对带宽达到52.3%,电压驻波比(VSWR)小于2.0的频带范围为1.20~2.05 GHz,天线体(不含天线罩)高度仅为17 mm(0.068λ_(max))。在整个带宽内,方向图保持稳定,且在方位面和俯仰面±60°内增益均大于0 dB。In response to the demand for measurement and control of high-speed near-space vehicles,a broadband low-profile missile-borne embedded conformal antenna with light weight,small size,low profile,simple processing,low cost,and easy integration with active circuits is developed.It is conformal with the projectile body through a conformal radome.The antenna adopts the form of a printed dipole,which is coupled with a metal structural wall conformal to the radome to effectively reduce the profile height of the antenna.The relative bandwidth of the antenna reaches 52.3%,the bandwidth of the VSWR below 2.0 covers the 1.20~2.05 GHz band,and the height of the antenna(without the radome)is only 17 mm(0.068λ_(max)).In the entire bandwidth,the pattern remains stable,and the gain is greater than 0 dB within±60°of the azimuth plane and elevation plane.
