Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

This paper presents the defected ground structure (DGS)-based band-stop filter (BSF) which is developed using RO4350B and has a small board area of 20 × 10 mm2. The performed analysis of the proposed DGS shape shows that the size of the DGS has a huge impact on the quality factor. The cascades of the defects and incorporation of external capacitors aid in achieving the dual-band BSF. Furthermore, the developed BSF demonstrates the ability of wide-band rejection from 6.45 GHz to 12.75 GHz.
