Abstract

In this paper, we propose a novel ultra-wideband Wilkinson power divider with symmetric defected ground structure (DGS) having frequency band-notch characteristic. The Wilkinson power divider was invented in 1960 and has wide applications in microwave circuits and antenna feeds. But it has a narrow bandwidth. Several schemes have been devised to increase its bandwidth. The main proposal used series connection of several sections having considerably increased bandwidth and high isolation between outputs for equal power divider. We use connection of three sections to obtain the UWB Wilkinson power divider. It is well known that the DGS of the microstrip line is implemented by making artificial defect on the ground and the ground defect provides a resonance property in transfer characteristic. In the microstrip line, DGS on the ground plane provides band rejection characteristic at some resonance frequency corresponding to the size of defect on the ground. In this paper, band-notch characteristic is achieved by inserting a symmetric spiral DGS under the microstrip line of the power divider. Experimental results of the constructed prototype are presented.
采用对称缺陷接地结构的带缺口超宽带1 ~ 4威尔金森功率分压器
本文提出了一种具有频带陷波特性的对称缺陷接地结构(DGS)的超宽带威尔金森功率分压器。威尔金森功率分配器发明于1960年,在微波电路和天线馈电中有着广泛的应用。但是它的带宽很窄。已经设计了几种方案来增加其带宽。主要建议使用串联连接的几个部分,具有相当大的带宽增加和输出之间的高隔离等功率分配器。我们采用三段连接的方式得到了超宽带威尔金森功率分配器。众所周知,微带线的DGS是通过在地面制造人工缺陷来实现的,而地面缺陷在传输特性上具有共振特性。在微带线中,地平面上的DGS在与地缺陷大小相对应的谐振频率上提供带抑制特性。本文通过在功率分压器的微带线下插入对称螺旋DGS来实现带陷波特性。最后给出了样机的实验结果。
