摘　　要：RFID读写器天线的小型化一直是研究的热点之一,利用HFSS进行了一款手持RFID读写器天线的设计。通过在微带天线的贴片以及在接地板上开槽,同时在贴片上面加载高介电常数介质基片的技术,设计出了一款小型紧凑的RFID矩形微带天线。它的尺寸仅为传统微带天线的68%左右,10dB回波损耗阻抗带宽50MHz,该天线能满足RFID系统的需求。The miniaturization of the RFID antennas is a hot research focus. An antenna used in the hand-held RFID reader was designed by HFSS. With the loading of a high-permittivity superstrate layer, the slots opening on the floor and the slits cut in the patch, a compact rectangular microstrip RFID antenna can be designed. The antenna size reduced to be -68% times that of a conventional patch antenna,the impedance bandwidth determined from a 10- dB return loss is found to be about 50MHz. The antenna can meet the requirements of the RFID systems.
