Abstract

In this paper, a design method for a compact slot antenna for 5.8 GHz RFID band (5.725 5.875 GHz) is studied. The proposed slot antenna is size-reduced by bending both ends of the straight slot in  -shape, and a rectangular feed patch is located inside the slot. The effects of slot length, location of feed patch, and width and length of feed patch on the antenna performance are examined. A prototype antenna with optimized parameters for 5.8 GHz band is fabricated on an FR4 substrate and tested experimentally to verify the results of this study. The experimental results show that the frequency band for a VSWR 0 dBi within the frequency band. 키워드 : 평면 안테나, 슬롯 안테나, RFID 안테나, 소형 안테나 Key word : planar antenna, slot antenna, RFID antenna, compact antenna Journal of the Korea Institute of Information and Communication Engineering 한국정보통신학회논문지(J.
