摘　　要：设计了一种新型平面超宽带缝隙天线.通过渐变缝隙及其加载来降低天线频率,拓展工作频带,从而实现天线的小型化与宽带化.实验测试结果表明,该天线回波损耗小于-10 d B的相对测试带宽达到了110%(3.1-10.6 GHz),该频带的测试增益高于1.48 d B,最高可达7.2 d B,而天线尺寸仅为15mm×25mm.天线馈电便利,工艺简单,成本低廉,可广泛用于近距离高速宽带无线通信系统.A novel planar UWB slot antenna has been designed, whose operation center frequency was de-creased by replacing the uniform slot with tapered slot, and bandwidth was broadened by loading a slot. As a result,a significant miniaturization and broader bandwidth of the proposed anterma has been achieved. The experiment results show that relative measured bandwidth of 110% （3. 1-10. 6 GHz） with return loss less than -10 dB, testing gain over 1.48 dB up to 7. 2 dB have been obtained with small size of 15mm×25mm. The proposed antenna can be widely applied to a short range communication system with high speed due to its advantages like ： feeding convenience, simple process and low cost.
