A wideband implantable antenna for 2.4 GHz ISM band biomedical application
In this study, a single-fed wideband implantable antenna that operates at the 2.4 GHz ISM band is designed for biomedical applications. The impedance bandwidth enhancement is achieved by combining two modes. One is the fundamental mode of center microstrip antenna, and anther additional mode is attained by the outside loop. The simulated impedance bandwidth and radiation patterns are studied in a cubic skin phantom. The simulated impedance bandwidth below −10 dB ranges from 2.24 to 2.59 GHz (35%). The proposed antenna mainly radiates in the off-body direction and has a peak gain of −20.8 dBi at boresight. The influence of dielectric properties and implant depth are also discussed. The sensitivity studies indicate the stability of our antenna.
