设计并分析了一种适用于超宽带无线应用的小型平面印刷天线。所提出的天线是由一个圆形贴片与圆形开口环槽逐渐变化的宽度，一个U形槽，一个小条槽，和一个分段接地平面与三个狭缝。为了展宽带宽和产生陷波，在天线辐射贴片上引入了三种不同类型的缝隙，并在缺陷接地层上嵌入了多个缝隙。仿真和实测结果表明，该天线具有2.9 ~ 13.0 GHz的带宽（回波损耗小于-10 dB），具有3.30-3.70 GHz（WiMAX频段）、4.50-4.83 GHz（INSAT/超扩展C频段接收频率）和6.67-7.15 GHz（INSAT/超扩展C频段发射频率）三个陷波频段。此外，所提出的天线已经实现了5.50 dBi的平均峰值增益和稳定的准全向辐射方向图。© 2015威利期刊公司.微波光学技术快报57：2056-2060，2015
A novel compact planar printed antenna is designed and analyzed for ultrawideband wireless applications. The proposed antenna is constructed by a circular patch with a circular split‐ring slot gradually varying the width, a U‐shaped slot, a small strip slot, and a segmental ground plane with three slits. To broaden the bandwidth and produce notches, three different type slots are incorporated in the antenna radiating patch, and multiple slits are embedded onto the defected ground plane. The simulated and measured results show that the antenna yields a wider bandwidth ranging from 2.9 to 13.0 GHz (the return loss less than −10 dB) with the three notched bands of 3.30–3.70 GHz (WiMAX band), 4.50–4.83 GHz (Receiving frequency for INSAT/Super‐Extended C‐band), and 6.67–7.15 GHz (Transmitting frequency for INSAT/Super‐Extended C‐band). Furthermore, the proposed antenna has achieved average peak gain of 5.50 dBi and stable quasi‐omnidirectional radiation patterns. © 2015 Wiley Periodicals, Inc.
