Analysis of Filtering Characteristics for Coplanar Symmetrical Meander Lines

This paper presents an analysis of the filtering characteristic for a coplanar symmetrical meander lines structure. The effects of geometrical parameters, which are length of vertical and horizontal elements as well as the distance of the gap between two symmetrical lines, on the filtering property of the structure are discussed. A novel direct derivation of the filtering performance of the coplanar configuration based on our proposed circuit model is also addressed. The mentioned analysis could be a useful guidance in the design stage of a uniplanar filter to enhance the signal and power integrity as well as immunity of Integrated circuits
