Abstract

In this research article, a novel double-split elliptical split ring resonator (DS-ESRR) is proposed to achieve frequency-notching behavior of ultrawideband filtenna, where the semimajor and minor axes of the ellipse are taken as a bivariate random variable and expressed in Ramanujan’s correction coefficient so that more degree of freedom is available for choosing degenerated impedance and thus for variable frequency-notching applications. To verify this hypothetical method, finite sets of variables for DS-ESRR are presented in this proposed work, and a mathematical expression is formulated to estimate the resonant frequency of the DS-ESRR, such that for practical applications, frequency-notching parameters can be easily estimated accurately rather than previously used SRR like circular or square-shaped geometry. DS-ESRR is deployed at the back of a CPW-fed ultrawideband antenna for notching filter application, and the computed data is compared with the eigen mode simulation results which reveal good agreement with each other.

具有带挡特性的旋转双分裂椭圆 SRR 系统分析

本研究文章提出了一种新型双分裂椭圆分裂环谐振器（DS-ESRR）来实现超宽带滤波器的频率消隐行为，其中将椭圆的半长轴和小轴作为双变量随机变量，并用拉马努扬修正系数表示，这样就有更大的自由度来选择退化阻抗，从而实现可变频率消隐应用。为了验证这种假设方法，本研究提出了 DS-ESRR 的有限变量集，并通过数学表达式估算了 DS-ESRR 的谐振频率，从而在实际应用中可以轻松准确地估算出频率消隐参数，而不是之前使用的圆形或方形几何形状的 SRR。DS-ESRR 部署在 CPW 馈电超宽带天线的背面，用于陷波滤波器的应用。
