In this paper, a novel low-profile RFID antenna is proposed. Based on original microstrip patch antenna, the tag antenna adopts a shorted stub and H-shape slot. Implementing a shorted stub can easily match the impedance of RFID chip. Using H-shape slot increases the length of current path on patch, miniaturizing the tag antenna. The size of the proposed antenna is 62 × 18 × 0.79mm3 and its simple...
Electromagnetic modeling and simulation is performed for a miniaturized patch antenna which includes a lossy dielectric substrate and layered thin-ferrite-film superstrate above microstrip. The structure is of multiscale and multimaterial feature and the system matrix may not be well-conditioned if surface integral equations (SIEs) are used to describe the problem. This work formulates the problem...
Tunability analysis based on electromagnetic modeling and simulation is performed for a miniaturized patch antenna loaded with self-biased magnetic films. The antenna includes a lossy dielectric substrate and layered thin-ferrite-film superstrate above microstrip. The structure is of multiscale and multimaterial feature and the system matrix may not be well-conditioned if the problem is described...
