摘要
提出了一种新型超宽带折合环形天线的设计。该天线采用共面波导馈电,易于与其他微波电路集成在一起;通过引入五边形的折合环结构,该天线的工作带宽较常规的折合环天线提高了一倍以上;通过数值计算研究了某些尺寸参数对天线输入特性的影响,在计算的基础上通过大量的实验详细研究了天线的频域工作特性。计算与实验的结果表明,该天线具有超过4.75:1的工作带宽和全向辐射特性,因此是一种有实用意义的超宽带天线。
Design of a novel ultra-wideband folded loop antenna was proposed.It was fed by coplanar waveguide and can be easily integrated with other microwave circuits.By introducing a pentagonal folded loop,the bandwidth of the an-tenna is improved twice than that of conventional folded loop antenna.Parametric study is carried out numerically by us-ing EM simulators.Based on numerical results,the antenna is also studied experimentally.As can be seen,an operation bandwidth of over 4.75：1 is obtained.The presented antenna may be practical for ultra-wideband applications.
