[天线]A novel planar microstrip antenna design for UHF RFID

Abstract .>Gq/[c0|  
Passive UHF RFID tags suffer from performance degradation when placed near s"*zyLUUo  
conductors and high dielectric substances. Microstrip RFID tags offer a potential k+f!)7_  
solution to this metal-water problem associated with passive UHF RFID tags. pE[ul  
However, their use is limited by narrow bandwidth, manufacturing complexity, h1^q};3!W\  
because of, the need cross-layered construction and therefore cost. We present a new j{C+`~O
 
antenna and matching circuit design using balanced feed that eliminates any reference 7q<I7Wt
