This three-year sub-project is to accomplish the following works: (1) Tag antenna designs for certain RFID applications, including: miniature omni-directional tag antenna, miniature embedded tag antenna, metal mounting tag antenna, and near and far field tag antenna. (2) To enhance the performance on tag reading, several reader antennas will be designed, such as antennas for broadband, high gain, reconfigurable pattern, reconfigurable polarization, beam switching and near-field identification. Also, some RF circuits, including power divider, RF switch, directional coupler, phase delay transmission line and Bulter Matrix will be designed by using artificial transmission lines and right/left handed transmission lines. (3) For evaluate the performance of the RFID system, the technologies of the RFID static test and antenna interference test will be developed, which may be applied to obtain maximum readable range, determine the proper locations of the tags, measure antenna interferences, etc. (4) To improve the readability of the RFID system, the parameters of the reader will be tuned by using the low-level reader protocol (LLRP). (5) To ... |
