This article presents a wearable microstrip patch antenna developed for biomedical applications. The operating frequency of the antenna is within the Industrial, Scientific, and Medical (ISM) band at 2.4 GHz. Two substrate types are used while implementing the proposed antenna; Epoxy FR-4 and Rogers RO4003C. The first substrate, Epoxy FR-4 has 4.4 dielectric constant, 1.6 mm thickness, and 0.02 loss tangent. At the same time, the second one is Rogers RO4003C, with a 3.55 dielectric constant, 0.813 mm thickness, and 0.0027 loss tangent. The selection is carried upon which type gives better performance from the point of electrical losses seen in matching the antenna input to the impedance of the transmission line connected to it. Antenna optimization is done using a High-Frequency Structure Simulator (HFSS) with an emphasis on delivering a return loss (S11) level of less than −10 dB in addition to a Specific Absorption Rate (SAR) of less than 1.6−W/kg as per the Federal Communication Commission (FCC). Two antenna designs were attempted to boost the criteria mentioned above; the design with the best performance was selected for fabrication. The designed antenna’s efficacy is proven by experiments on the human body considering real-time settings. The simulation and experimental results are well matched.

摘要

This article presents a wearable microstrip patch antenna developed for biomedical applications. The operating frequency of the antenna is within the Industrial, Scientific, and Medical (ISM) band at 2.4 GHz. Two substrate types are used while implementing the proposed antenna; Epoxy FR-4 and Rogers RO4003C. The first substrate, Epoxy FR-4 has 4.4 dielectric constant, 1.6 mm thickness, and 0.02 loss tangent. At the same time, the second one is Rogers RO4003C, with a 3.55 dielectric constant, 0.813 mm thickness, and 0.0027 loss tangent. The selection is carried upon which type gives better performance from the point of electrical losses seen in matching the antenna input to the impedance of the transmission line connected to it. Antenna optimization is done using a High-Frequency Structure Simulator (HFSS) with an emphasis on delivering a return loss (S11) level of less than −10 dB in addition to a Specific Absorption Rate (SAR) of less than 1.6−W/kg as per the Federal Communication Commission (FCC). Two antenna designs were attempted to boost the criteria mentioned above; the design with the best performance was selected for fabrication. The designed antenna’s efficacy is proven by experiments on the human body considering real-time settings. The simulation and experimental results are well matched.
