This article presents an innovative contribution, which is the design of a novel radio frequency identification chipless tag characterized by a reduced size and a multifrequency response. It consists of a microstrip grounded structure based on a circular patch coupled with meandered metal strip. The adopted approach is an encoding frequency approach that ensures a capacity of 20 data bits in the ultra wideband. The main aim of this contribution is to introduce a novel configuration resulting from the study of the classic principles of the chipless tag design. It focuses on the design of an encoding surface associated with the same shape having the role of the transmitter/receiver antenna in order to mainly gain time to work on another tag component. The tag is analyzed, optimized, and measured to validate its feasibility and to prove the possibility of its commercial application.
