Design of a Miniaturized Implantable Antenna in the MICS Frequency Band
A new type of flexible implanted antenna in the MICS frequency band is proposed.The dielectric plate material of the antenna is flexible polyimide,the radiation part is a circular metal strip line,and the grounding ground is a rectangle with circular corners.The antenna is fed by a coplanar waveguide,and the overall size is 12×7×0.24mm3.At the same time,this article also analyzes the effects of insulation materials,human organ tissues,the implantation depth of antenna,the thickness of dielectric plate,radiation unit line length and line width on antenna performance.The final measured antenna bandwidth is 270-420MHz,which can cover the MICS frequency band and can be applied to small implantable medical devices.
