摘要

提出了一种具有蜗牛状槽的超宽带印刷槽天线。实验结果表明，所提出的微带馈线缝隙天线可以实现非常宽带的工作。以10db回波损耗决定的阻抗带宽接近10460 MHz，约为150.07%。在E面和h面测量了辐射图，得到了槽状辐射图。从测量结果来看，在3.1 ~ 10.6 GHz的宽阻抗带宽范围内，天线增益变化大于3dbi。

Microstrip-line-fed snail-like slot antenna for ultra-wideband operation

An UWB printed slot antenna with a snail-like slot has been presented. Experimental results show that a very wideband operation of presented microstrip-line-fed slot antenna can be obtained. And the impedance bandwidth, determined by 10 dB return loss, reaches nearly 10460 MHz, which is about 150.07%. The radiation patterns have been measured and presented by E- and H-planes, and slot-like patterns can be obtained. From measured results, antenna gain variation is larger than 3 dBi in the range of 3.1−10.6 GHz within this wide impedance bandwidth.
