We propose a novel chipless RFID tag composed of topologically modified uniplanar U‐folded dipoles with inclined arms. This topology reduces the interelement mutual coupling and provides a significantly better amplitude uniformity and frequency stability of tag RCS response when logical “ 0 ” is coded by removing particular scatterers from the array. Simultaneously, it provides a higher encoding capacity in unit frequency range than the arrays composed of original U‐folded dipoles with parallel arms, yet at the expense of small RCS magnitude reduction.© 2016 Wiley Periodicals, Inc.
