Experimental radiation pattern analysis of a text antenna for RFID IC Transponders

In this work, an experimental radiation pattern analysis of a text antenna based on meander-shape dipole structure 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.
