This paper aims to investigate the performance of suggested circular patch microstrip antennas in healthcare systems. The proposed approach has involved using various substrate materials, including epoxy (FR4), polycarbonate, polyimide, rubber, and silicon, to construct the employed configuration of the microstrip antenna and testify the influence of electrical properties of the substrate material on the performance of the proposed microstrip patch antennas. The chosen antennas were simulated in conjugate with the human body tissue model using the circuit simulation (CST) studio in the frequency band of (2-3 GHz) to meet the demand of the industrial. scientific, and medical (ISM) frequency band requirements. Upon comparing the five employed materials of substrates via the simulation process, it was evident that the polycarbonate material gives the most favorable outcomes among other substrate materials in terms of reflection coefficient parameter (-45.6 dB), voltage standing wave ratio (1.0103), besides gain value (6.37dBi) but it didn't meet the demand of medical requirements. The simulation results showed the availability of the performance requirements of the proposed microstrip patch antenna using (FR4) as a dielectric material. The obtained results closely match the recommendation of the safety factor parameters in medical applications related to the specific absorption rate (SAR) factors. [ABSTRACT FROM AUTHOR] |
