Metamaterials microstrip patch antenna for wireless communication RFID technology

Abstract

ABSTRACTThis article is specialized to highlight the method of miniaturization and improvement the patch antenna using the complementary metamaterial. This method is presented by two different techniques. The first technique is composed a structure of patch antenna integrated in its surface a cell of complementary split ring resonator. This resonator is placed at the middle of the radiating patch in parallel with the transmission line and with a variable angle of orientation. The objective is to find the ultimate angle where the best results are obtained on improving the characteristics of the considered antenna. This motif widespread at the traceability applications by wireless communication for RFID technology at the operation frequency 2.45 GHz. In the second technique, were integrated at the surface of antenna a homogeneous and periodic array of complementary split ring resonators using the same position and the supreme orientation found in early studies. The advantage of the latter technique is to indicate the effect of increasing the number of resonators on the performance patch antenna and show the specifications and characterization of each technique proportionally at the two interesting factors miniaturization and improvement. Our contribution is based on studies and empirical and theoretical tests often presented in this article. All simulation results were made by the CST Microwave Studio. © 2015 Wiley Periodicals, Inc.
