Chiral crank inclusions <br>are distributed along both sides of the strip and the corresponding results are compared with those obtained by other elements commonly <br>used to create EBG media, mushroom-type structures. A single row of high chirality structures on both sides of a transmission line <br>produces a band gap with a wider bandwidth than that obtained by the inclusion of other elements commonly used to create EBG media,<br>such as mushroom-type structures. Unlike what happen with mushroom-type inclusions, more rows of chiral elements do not change significantly <br>the central frequency and bandwidth of the band gap. The proposed structure works in X-Band (8.2-12.4 GHz) and it is easily adaptable to <br>other frequencies by changing the size of the crank inclusions. Several samples have been made in FR-4 printed circuit board and a good <br>agreement has been found between numerical analysis and experimental measurements.</pre> ER -
