Disturbance of metal and other media on radio frequency signal has a great effect on the performance of passive UHF RFID system in application. By separating patch antenna from metal surface, a ground-independent RFID tag was constructed using 3D microstrip antenna model, but manufacturing complexity and cost of RFID tag structure were increased.

The new antenna can not only decrease the complexity of manufacturing the RFID tag, but also supply tag's compatibility to different environment material in application.

The coreless coil inductance calculation of MEMS in human body was proposed, focusing on the mutual inductance of non-coaxial coils. The effects on the mutual inductance due to main geometric parameters, such as gap, obliquity and radius, were analyzed. The numerical results indicate that mutual inductance decreases with the increase of axial and radial gaps and the influence of axial gap on mutual inductance is much bigger than the radial one; with the increase of obliquity, mutual inductance decreases, and when obliquity angle is equal to 90°, it is nearly zero; when coil radius varies, mutual inductance has a maximum. Furthermore, a tri-axial moving platform is put forward in which gap and obliquity can be adjusted easily and accurately. On the basis of the above, a mutual inductance measuring system is established, and the testing results are consistent with the calculation.
