A U-Shaped Loop Antenna for In-Body Applications

摘要

This paper describes a flexible U shaped loop implantable antenna for in-body applications. The proposed antenna having a bandwidth which covers the Med Radio band (402-405 MHz) which is the standard band for Bio Implantable applications, ISM band 433.050-434.79 MHz. The antenna is made of polyamide substrate having a size of 3.3 mm radius and height of 13.5 mm. The simulated antenna is having a -10 dB Bandwidth of 158 MHz (335-493 MHz) resonates at 402 MHz having proper VSWR throughout the bandwidth. The Radiation pattern of this antenna is directional having a gain of -31.16 dB.
