| description | An inductively coupled feed novel technique is proposed to enhance the performance of RFID tag antennas. The applied feeding concept comprises of two opposing symmetrical U-shaped structures to feed a radiating body. It is a simple alternative to effectively match between the antenna impedance with the chip impedance from the flexible augmentation of equivalent inductance to the radiating body. The proposed feeding method offers better expectation of performance among antenna size, impedance, and gain at the size of 50 × 70 × 1.6 mm3. The peak gain of the proposed tag antenna is 2.5 dBi at its operating frequency, which is higher among conventional tag antennas. Measured results indicate that this tag antenna has a good impedance matching characteristic at 904-937 MHz (power reflection coefficient better than -3 dB). The comparison between the simulation and measurement results verified the proposed technique capability to improve overall performance of the tag antennas. |
