[天线][分享]Impedance Characterization of RFID Tag Antennas and Application in Tag Co-Design

Abstract－In this paper, an experimental methodology for the V "h +L7T  
characterization of the impedance of balanced RF identification u.Dz~$T  
(RFID) tag antennas is presented, and the application of the proposed
IO-Ow!  
method in RFID tag co-design is demonstrated. The balanced DR<9#RRD  
tag antenna is considered as a two-port network and the G'A R`"F  
impedance of the antenna is characterized using network parameters. | %Vh`HT  
In the measurement, the antenna is connected to the two ports }pu27F)&  
of a vector network analyzer through a test fixture. The influence ?5 7Sk+  
of the test fixture is deembedded by using a port-extension technique
I2 P@L?h  
and the antenna impedance can be extracted directly from D d</`iUq  
the measured -parameters. D}X\Ca"h  
The proposed method is useful in practical RFID applications ixD)VcD-f  
for co-designing the RFID tag with the attached platforms for z' >_Mc6  
enhancing the tag performance. An example of co-designing ySDH"|0  
an ultra-high-frequency RFID tag with a plastic Sushi plate is n7-6- #  
demonstrated. The co-designed tag antenna achieves conjugate [IhYh<i  
matching with the application-specific integrated circuit so that y h9*z3  
the reading range of the RFID tag is greatly enhanced. {{p7 3 'u

下来看看，上次下的打不开，郁闷啊

请再试试看，因为我尝试下载后是没问题的 U@)eTHv}6  
不行的话再留电子邮箱，我在寄给您

上次下的打不开

看看再论。

看看再论。
