摘要

提出了一种单层频率选择表面的超宽带方圆单极天线。所提出的结构由方形圆形几何结构组成，工作在高达146%的超宽带中。为了提高增益，在辐射元件下方采用FSS表面，该辐射元件由一个尺寸为10mm × 10mm的单元格6×6排列组成。所提出的单体蜂窝具有3.3 GHz到10.5 GHz的带阻响应范围。采用FSS反射器的UWB SC天线，下带增益从2db提高到5db，上带增益从4db提高到8db。基于FSS的天线总体尺寸为62.5\text{mm} × 62.5\text{mm} × 1.6$ mm。所提出的天线结构具有超宽带宽和增强增益的优点，可以成为超宽带(UWB)技术新兴应用的优秀候选者。

UWB monopole antenna backed by single layer FSS for high gain antenna applications

In this paper, an ultra-wide-band square circular (SC) shaped monopole antenna with a single-layer frequency selective surface (FSS) is presented. The proposed structure consists of square circular geometry operating in ultra-wide bandwidth up to 146%. To improve the gain, the FSS surface is employed below the radiating element which consists of a 6×6 arrangement of a unit cell having a size of 10mm × 10mm. The proposed unit cell has band stop response ranges from 3.3 GHz to 10.5 GHz. The UWB SC antenna with an FSS reflector demonstrated an improvement in gain from 2 dB to 5 dB in the lower band and from 4 dB to 8 dB in the upper band. The overall size of FSS based antenna is $62.5\text{mm}\times 62.5\text{mm}\times 1.6$ mm. The proposed antenna structure with its merits of ultra-wide bandwidth and enhanced gain can be an excellent candidate for the emerging applications of ultra-wide-band (UWB) Technology.
