Diseño de una etiqueta pasiva sin chip para aplicaciones RFID en UWB.

Abstract

In the present work we propose the design of a passive tag without a chip for Radio Frequency Identification (RFID) applications in Ultra Broadband (UWB). Chapter 1 discusses the theory of microstrip antennas and their broadband design specifications. Chapter 2 outlines the fundamentals of Radio Frequency Identification, its use in UWB applications and explains the use of spectral identification in this technology. In Chapter 3, the design of the label is proposed; the receiving and transmitting antennas are simulated individually, together with the grooves in the ground plane and in the radiating element to obtain the spectral signature, in the range of 3.1 to 10.7 GHz. This work is exploratory when exploring the characteristics of a passive tag without chip for RFID applications in UWB and is descriptive when analyzing and evaluating the technologies to implement these systems and determine the optimal parameters according to their needs. The empirical-analytical paradigm and a quantitative approach are applied when using mathematical calculations in the design. This research is experimental because the applied variables are altered to perform the respective analysis.
