设计了一种小型双阻带超宽带天线。天线采用共面波导(CPW)馈电的地板结构,地板由两个半椭圆构成,从而实现了超宽带天线及小型化。通过开双U型缝隙实现了双阻带特性,阻带带宽分别是650 MHz和590 GHz。天线实物测量结果表明,天线驻波比<2的带宽为2.97~12.75 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。

This paper presents a simple dual band-notched circular disc monopole (CDM) ultra-wideband antenna with CPW-feed and the ground plane consists of two semiellipses,thus achieving the ultra-wideband antenna and miniaturization.By cutting two U-shaped slots on the feed line and patch,two notched bands of 650 MHz and 590 GHz are achieved.The measurement result of physical antennas show that with the standing wave ratio (VSWR) < 2 the bandwidth is 2.97 GHz to 12.75 GHz and the antenna gain is high within the frequency band with satisfactory radiation properties.A good agreement is achieved between simulated and measured antenna characteristics.
