The use of Composite right/left handed (CRLH) metamaterial based transmission lines (TL) for high frequency applications can improve the magnetic field intensity and uniformity. This can be achieved independent from its physical length, contrary to the traditional microstrip TL. In this work we compare the |B1| and |E|-field of the CRLH TL with a common microstrip TL when used in an array of two elements. Three arrays with different lengths were compared, resulting in better field uniformity for the case of the CRLH TL.
