Printed H-Antenna with Parasitic Element for RFID Systems

In this work, we present a new design of split printed H-antenna for RFID (Radio Frequency Identification) applications, at 2.45 GHz. The HFSS electromagnetic simulation software is used to optimize of geometric parameters and to determine the antenna radiation characteristics. The CST electromagnetic simulation software is also used to compare and validate the results. The results show that the reflection coefficient reaches a level of -36 dB at 2.45 GHz with a narrow bandwidth of 42 MHz. A prototype of the antenna was produced and the experimental results show a good agreement with numerical results.
