中文摘要：

给出了一种两宽带天线共用一个口径的设计．天线制作在420×200mm^2的PCB板上，其中一副天线由阻抗加载的矩形及倒L形金属片构成，两者之间使用了一个低通匹配网络进行连接．此天线实现30～600MHz驻波比小于3的宽带匹配，其中86～110MHz之间为陷波设计．另外一副天线采用开式套筒结构，实现了800～1200MHz驻波比小于2．2的设计．利用天线1的低通匹配网络作为天线2的开式套筒，从而实现了共口径设计．

英文摘要：

A design of two wideband antennas sharing one aperture is proposed. One antenna consists of a rectangle impedance loaded monopole, an inverse ＂L＂ shape impedance loaded monopole and matching network, which coves 30-600MHz （VSWR 〈 3） and possesses a band-rejection characteristic at 86-110MHz. The other antenna is an open form sleeve and covers 820- 1200MHz with VSWR 〈 2.2.
