摘要：
We have developed a miniaturized implantable ferrite antenna, operating in the industrial, scientific, and medical band (2.4-2.5 GHz). The dip-coated NiCo ferrite films effectively reduces the antenna resonance by 110 MHz, with a 4.2 dB reflection coefficient improvement as compared with an antenna without ferrite. The ferrite antenna also reveals a 6 dBi and 35 MHz improvement in realized gain and 210 dB bandwidth, respectively, at resonance. The effects of ferrite film loading on antenna performance are further investigated with parametric simulations and experimental comparisons. (C) 2016 Wiley Periodicals, Inc.
