【摘要】 本文设计了微带馈电和共面波导馈电的平面宽槽超宽带天线。采用阶梯式过渡微带拓宽了天线的阻抗带宽,分析了开槽大小对天线驻波的影响。槽和馈电单元都采用了由椭圆和矩形构成的混合结构。这两种天线在实现小型化的同时,满足了FCC规定的超宽带标准。文章的最后部分采用寄生条带和贴片开槽的方法,实现了天线的双阻带特性。更多还原

【Abstract】 This paper design two novel wide-slot antennas fed by CPW and Microstrip line. Impedance bandwidths of the antennas were broadened by adopting step-by-step transition feeding structure. Effects of varying the slot size on VSWR have been analyzed. The hybrid structure constituted of the elliptical and rectangular shapes has been adopted in the antenna design. Both of the antennas achieve the miniaturization and satisfy the FCC requirements of ultra-wideband standard. Finally in this letter,the parasitical strip and the folded slot have been used to implement the dual band-notched characteristic.更多还原
