Abstract: This work focuses on designing and improving a wearable textile microstrip patch antenna that operates at 2.43 GHz for use in biomedical Body Area Network (BAN) applications. The antenna is built on a polyester substrate and was initially simulated using Altair FEKO software.In free-space conditions, the antenna performed reasonably well, showing good impedance matching with a reflection coefficient of 11.7 dB and a VSWR of 1.7. However, when tested on a human body model, its performance dropped due to the influence of body tissues. The reflection coefficient worsened to 5.7 dB and the VSWR increased to 3.16, clearly indicating detuning caused by body loading.To overcome this issue, the ground plane of the antenna was optimized, which significantly improved its performance. The resonance was enhanced to 20 dB, and the VSWR reduced to 1.2, indicating much better impedance matching. Additionally, an Artificial Magnetic Conductor (AMC) layer was introduced to reduce unwanted back radiation and lower the Specific Absorption Rate (SAR), making the antenna safer for wearable use.With the AMC layer, the antenna achieved SAR values of 1.23 W/kg (1 g) and 0.71 W/kg (10 g), which are lower than many conventional textile antennas. When compared with existing studies, the results show that incorporating AMC not only improves safety but also ensures more stable performance. Overall, the proposed antenna design is well-suited for BAN applications and offers a practical solution for safe, reliable, and continuous health monitoring systems.
