Design of Dual Band RFID Antenna Reader by Modified H-Shaped Resonator

A printed microstrip-fed monopole RFID (Radio Frequency IDentification) antenna with dual bands is presented. By embedding a modified two h-shaped resonator, the first on left and the other on right of the microstrip feed line with partial ground plane. The antenna designed and simulated using CST (Computer Simulation Technology) microwave studio software, fabricated on Rogers's 4003c substrate with dimensions 33x25mm, dielectric constant of 3.38 and thickness of 0.813mm by etching and photolithography. The measurement showed that the designed antenna operate at (2.4GHz and 5.8GHz) with good return loss.
