    Abstract

    In this paper, we present a way to increase the operational efficiency of the UHF-band RFID system. A Flat reflecting surface is placed behind a small UHF antenna and changes a low antenna gain to a high one. We set 920 MHz as the target frequency and obtain benefits of 6.5 dB-gain increment and relatively a small volume for wavelength of 32.6 cm. It is shown that both the source antenna and the metamaterial-inspired reflecting surface are planar, which makes the system easy to develop for a high gain and maintenance.
