摘　　要：文中给出了一种双频宽带平面天线设计。该天线由矩形加载单极子,倒L形加载单极子和匹配网络组成,频带覆盖30 MHz～88 MHz、107 MHz～500 MHz,带内驻波比<3,增益分别>-22 dBi和-10 dBi。该天线具有宽频带、小型化和低剖面等特点,可以用作机载天线使用。A dual -frequency wideband planar antenna is proposed. This antenna consists of a loaded rectangle monopole, an inverse ＂L＂ shape loaded monopole and a matching network. It covers 30 MHz--88 MHz with the gain 〉 -22 dBi and VSWR〈3 and 107 MHz--500 MHz with the gain 〉 -10 dBi and VSWR 〈 3. This antenna has such characteristics as wide band, compact structure and low profile so that it can be used for the airborne antenna.
