Microstrip Yagi Antenna on Papery Substrate for RFID Tag Antanna |
| |
| Abstract: | A microstrip Yagi structure of RFID tag antenna on papery substrate is proposed. Impedance and radiation patterns of the tag antennas are simulated with MoM as the array structure changes, and a microstrip Yagi tag antenna with meander-line structure is manufactured . Results of simulation and test show that RFID tag antennas with both meander-line and Yagi structure are easy to gain the impedance of conjugate matched to the tag IC, which is small in resistance and large in reactance. |
