In this work, an experimental radiation pattern analysis of a text antenna based on meander-shape dipole struc ture is presented. The use of text antennas can bring interesting technological advantages in terms of advertising, marketing and logistics. The planar antenna operates at UHF band and its shape is designed to represent the name of the Universidade Federal do ABC (i.e. Federal do ABC -UFABC). The radiation pattern performance of the antenna is evaluated by measurements in a tested built prototype inside at UFABC anechoic chamber.Index Terms-Planar antennas, dipole antennas, meander lines, RFID integrated circuit.

In this work, a metamaterial-based antenna is designed to operate at 2.5 GHz for RFID applications. The proposed device is composed by a circular antenna surrounded by fractal metamaterial structures placed at strategic positions, improving bandwidth and enhancing the antenna attunement at a desired frequency. The obtained results show that the use of the proposed antenna in RFID systems is very promising.Index Terms -RFID, metamaterial, fractal.
