A Miniaturized Implantable Antenna for Health Care Monitoring

This article outlines the creation, examination, and evaluation of a microstrip patch antenna uniquely tailored for medical observation setups operating at 2.45GHz. The antenna was manufactured utilizing Rogers RT/Duroid6010 of thickness of 0.254mm and a relative permittivity of 10.2, and the antenna spans dimensions of 4×5.5×0.254mm
³
. Through modeling and practical trials, it demonstrates exceptional characteristics within the Industrial, Scientific, and Medical (ISM) band. The antenna demonstrates an impressive return loss of 47dB and a peak gain of -33dBi, with a bandwidth spanning 20MHz centered around 2.45GHz. The uppermost simulated input power is 8mW to adhere with the FCC SAR limitations 1.6W/Kg.
