Abstract

A circularly polarized microstrip metallic patch antenna made reusing and recycling materials from construction debris is proposed, designed, fabricated and validated in this paper. Such device is used in RFID systems operating at the 902-928MHz UHF band allocated for International Telecommu- nication Union, ITU, Region 2, that includes North and South America. The antenna is composed of two stacked patches, a T junction based on microstrip lines and a ground plane, being those arranged in simple and low cost structure. Experimental and simulation results of this microwave device are presented and discussed.
