摘要

本文提出了一种紧凑的共面波导(CPW)馈电超宽带(UWB)印刷天线。该天线采用先进的基于分形结构的科赫形状，采用互补的分裂环谐振器(CSRR)蚀刻成单层，以获得双带陷波功能。同时结合新的馈电方法，对四种不同的天线设计进行了优化、仿真和测量。最终天线占地面积为20 × 26.4 × 0.81 mm2，阻抗带宽覆盖范围为3.1GHz至10.6 GHz, VSWR小于2,WiMAX为3.3-3.6 GHz, WLAN为5.15-5.35 GHz。超宽带天线在h面表现出良好的全向辐射方向图，在e面表现出与小偶极子相似的双向辐射方向图。

A novel CPW-fed fractal antenna for UWB with dual notched-bands

The paper presents a compact coplanar waveguide (CPW)-fed ultra-wideband (UWB) printed antenna with a dual band rejection. Implemented with developed fractal structures-based Koch shape, the proposed antenna uses a complementary split ring resonator (CSRR) etched into a single layer to obtain the dual band-notched function. Also integrated with a new feeding method, four different antenna designs are optimized, simulated and measured. The final antenna occupies a compact area of 20 × 26.4 × 0.81 mm2 and has an impedance bandwidth of covering from 3.1GHz to 10.6 GHz for VSWR less than 2 with dual unwanted band notches of 3.3-3.6 GHz for WiMAX and 5.15-5.35 GHz for WLAN. The UWB-antennas demonstrate good omnidirectional radiation patterns in the H-plane, and bidirectional patterns in the E-plane like those of a small dipole.
