摘要：
This letter presents a switchable near-field and far-field compact antenna based on ferromagnetic resonance, which can be used in radio frequency identification applications. By changing the bias magnetic field, the frequency point of ferromagnetic resonance can be adjusted to change the radiated power. With the artificial transmission line structure, the overall size is small. It has the advantage of a uniform magnetic field. Simulated results show that the proposed antenna works on the American radio frequency identification frequency band and realizes gain switching from -2.5 to 5 dB. It can generate a strong and uniform magnetic field in the NF region and provide a 5 dB FF gain. Compared with other antennas, ferromagnetic resonance is seldom used, but it has the advantages of easy manufacture and certain values for reference.
