摘要

提出了一种用于超宽带应用的辐射贴片上带u型槽和导体背平面的平面天线。通过在辐射贴片上切割u型槽来修改基本平面天线。在接地面上增加一个u型导体背板，作为寄生谐振器。通过插入优化的三角形狭缝和多狭缝接地平面，该天线的工作带宽从3.1 GHz提高到12.33 GHz，达到了120%的高分数带宽。天线的尺寸非常小，只有12 × 18 mm2。然而，它仍然可以产生非常宽的工作带宽。改进后的平面天线满足了3.1 GHz至10.6 GHz的超宽带(UWB)应用要求。本文对天线的重要参数进行了明确的定义。对仿真结果进行了观察和分析。总体而言，该天线在2.6 dBi至5.7 dBi之间的超宽带应用中产生可接受的增益。该天线还能产生稳定的近全向辐射方向图。

Planar Antenna with U-Shaped Slot on Radiating Patch and Conductor-Backed Plane for UWB Applications

Planar antenna with U-shaped Slot on Radiating Patch and Conductor-Backed Plane for UWB Applications is presented in this paper. The basic planar antenna is modifying by cutting a U-shaped slot on the radiating patch. A U-shaped conductor-backed plane is add on the ground plane and acts as parasite resonator. By inserting an optimized triangular slits and multi-slotted ground plane, the antenna produced a high fractional bandwidth of 120% with operating bandwidth from 3.1 GHz to 12.33 GHz. The antenna has very small size as 12x18 mm2. Yet, it still can produce very wide operating bandwidth. The modified planar antenna fulfills the requirement for ultra-wideband (UWB) applications which need operating bandwidth from 3.1 GHz to 10.6 GHz. The significant parameters of the proposed antenna are defined clearly in this paper. Simulated results are observes and analyzed. Overall, the proposed antenna produces acceptable gain for UWB application between 2.6 dBi to 5.7 dBi. Stable and near omni-directional radiation pattern are also produced by the antenna.
