摘要

提出了一种优化的共面波导(CPW)馈电超宽带(UWB)印刷辐射体。平衡的形状被集成到辐射部分,使得阻抗在预期带宽上以平衡的方式匹配。cpw馈电和天线部分都是在标准RT5870高频层压板上实现的。该辐射器在设计频谱(4.2 ~ 14.2 GHz)内具有良好的超宽带特性。这些特征包括几乎完全对称的模式,无侧瓣,对称轴平面无交叉分量,所有其他平面均无低交叉分量,平衡阻抗带宽和近4倍频的阻抗带宽。

A Novel CPW-fed Optimized UWB Printed Antenna
An optimized coplanar waveguide (CPW)-fed, ultra-wideband (UWB) printed radiator is presented. Balanced shapes are incorporated to the radiating section so that the impedance is matched in a balanced manner over the intended bandwidth. Both the CPW-feed and the antenna sections are realized on one single layer of standard RT5870 high frequency laminate. The radiator possesses good UWB-characteristics in the designed spectrum (4.2 to 14.2 GHz). These include nearly perfectly symmetrical patterns, no side-lobes, no cross-polar components in the symmetrical axial plane and low cross-polar components in all other planes, balanced impedance bandwidth, and almost 4 octaves impedance bandwidth.
