Abstract


The growth of the healthcare sector has attracted a lot of interest to biomedical telemetry. Without regular hospital check-ups and follow-up routine check-ups, it is now possible to remotely monitor a patient's physiological indications. This research work proposes an 18 mm3 implanted antenna with a mainly compact volume for biomedical applications. The performance of the antenna is entirely examined in terms of the SAR values, directive gain, Impedance Bandwidth, and reflection coefficient. The substrate material used in proposed antenna is FR4 epoxy resin, as FR4 plays an important part in adding the bandwidth of the antenna and is far cheaper than Rogers or any other relevant material, therefore giving the device an upper hand over other substrate accoutrement. The proposed antenna is configured to operate in the higher ISM band (5.725 GHz to 5.875 GHz) with an impedance bandwidth of 17.02%. Sorting pins and triangular slots on the patch surface have been introduced, which offer an ISM band, an excellent SAR value of 255.235 W/ Kg, a directive gain of -25.117 dB, and improving the performance of the suggested antenna. Using high frequency structure software (HFSS) tool, detailed analysis of the suggested implantable antenna has been carried out and thoroughly investigated for overall comparison and improvement.
