Gain improvement for rectangular horn antenna by using curved-woodpile metamaterial
© 2016 IEEE. This paper proposes the new technique of the metamaterial on the structure of the curved-woodpile Electromagnetic Band Gap (EBG) for gain improvement of a conventional rectangular horn antenna without its construction enlargement. The curved-woodpile EBG, which is the 3D volumetric stru...
