Abstract

Reducing the interference between ultra wideband (UWB) and existing wireless communication systems has become of importance recently. In this study, we propose an equal 1 to 4 power divider (PD) which enables the suppression of three different frequencies, 3.95, 5.2 and 5.8 GHz, in the UWB frequency band by means of U-shaped defected ground structure (DGS). In this respect, it is essential to provide steep band-rejection with high Q-factor. The authors have used a novel method to attain this goal using U-shaped DGS. Studies show that there is a relation between the line width and Q-factor of a given band-notched structure. Therefore, instead of using a 50-50-50 ohm configuration, a 50-100-50 ohm transformation is used which has a narrower line width in the middle of the PD providing a steeper suppression with a high Q-factor. The measured Q-factor compared to similar structures is higher having a value of 27.5 with more than 30 dB suppression.
一种采用u型DGS的超宽带1到4威尔金森功率分压器,具有三重高q带陷波特性
减少超宽带(UWB)与现有无线通信系统之间的干扰已成为当前的重要问题。在这项研究中,我们提出了一个相等的1到4功率分压器(PD),它可以通过u形缺陷接地结构(DGS)在UWB频段抑制3.95、5.2和5.8 GHz三个不同的频率。在这方面,必须提供高q因子的陡阻带。作者使用了一种新颖的方法来实现这一目标,即使用u形DGS。研究表明,给定带缺口结构的线宽与q因子之间存在一定的关系。因此,不使用50-50-50欧姆的配置,而是使用50-100-50欧姆的变换,该变换在PD中间具有更窄的线宽,提供具有高q因子的更陡峭的抑制。与同类结构相比,测量到的q因子更高,其值为27.5,抑制超过30 dB。
