| 摘 要： | 设计了一种小型双阻带的超宽带天线。采用由两个半椭圆和一个长条矩形复合的一种新型地板结构,从而实现了超宽带天线小型化。通过开双U型缝隙实现了双阻带特性,阻带带宽分别是540 MHz和610 MHz。天线实物测量结果表明,天线驻波比＜2的带宽为2.7~12 GHz,在整个频段内天线增益较高,同时方向图全向特性良好。天线的测量结果和仿真结果有较好的一致性。

| Abstract: | A novel miniature antenna design for ultra-wideband（UWB） applications is presented.The proposed compact antenna is achieved by exploiting a novel ground plane consisting of a small rectangle and two semiellipses.By cutting two U-shaped slots on the feed line and patch,two notched bands of 540 MHz and 610 are achieved.The configuration of the proposed antenna can provide an ultra wide voltage standing wave ratio（VSWR）2 bandwidth with satisfactory radiation properties.A good agreement is achieved between simulated and measured antenna characteristics. |
