Abstract

2.45GHz band is one of the frequency bands which are commonly used in RFID. In order to achieve an antenna with good performance in this band, based on improving the aperture-coupled-feed antenna structure, we introduce a high-impedance surface of microwave photonic crystal structure in antenna design. By novel structure and effective design idea, the antenna can maintain a high gain and has a better stability in a wider band. The size of the antenna will be reduced at the same time, so that the overall performance of the antenna will be more perfect. The experiment results show that the 2.45GHz-band reader antenna based on high-impedance surface proposed in this paper has good performance, and the novel structure and effective design ideas of the antenna have practical significance for the reader antenna design.
