【摘要】 本文提出了一种加载短路钉的X波段基片集成波导缝隙天线,分析了展宽天线阻抗带宽的方法。该天线通过在缝隙附近加载两个短路钉,使天线出现新的谐振频率,从而使得该基片集成波缝隙天线的阻抗带宽大大拓展。基于此加载短路钉的基片集成波导缝隙天线在9.8～11 GHz实现VSWR<2 (相对带宽为11.5%)。相比无短路钉的基片集成波导缝隙天线,该天线的阻抗带宽提高了33%,增益达到了5.5 dB。更多还原

【Abstract】 An X band substrate integrated waveguide slot antenna based on shorting-vias is proposed in this paper.Methods of enhanced-banwidth antenna design are introduced.A novel slot and two metallic-vias placed in the cavity are used, which improves the relative bandwidth of the antenna.By loading two shorting-vias in the cavity,the new resonant frequency formed.The impedance bandwidth of this SIW antenna range from 9.8-11 GHz with VSWR<2(the relative bandwidth is 11.5%),achieving 33% impedance bandwidth enhancement when compared to the antenna without shorting-vias.The peak gain of the proposed antenna is 5.5 dB.更多还原
