Dipole Antenna Design for UHF RFID Tags

Abstract

This paper presents a method to design UHF antennas for RFID applications. The paper proposes a step by step method that allow to select the adequate antenna topology according to the application and band, simulate and to design the lay out considering the metal and substrate material. The antenna here presented was designed for UHF application. The results obtained are in accordance with the theory; the input impedance and pattern were designed for RFID application.
