| Abstract: | Currently,each country has its own frequency allocation for RFID.For example,RFID UHF bands are:866~869 MHz in Europe,902~928 MHz in America,both 840~845 MHz and 920~925MHz in China.A dual-band passive tag antenna is designed,it can be used in both Europe and America.It is a couple feed structure antenna,which is broadband and easy to match the impedance of different chips.We also analyse the effect of the parameters which influnce the performance of the antenna.Simulation and test results demonstrated that the antenna is very practical. |
