Design of Wearable Antenna for Biomedical Telemetry Application

In this paper, a dual-band low profile flexible microstrip patch antenna with low specific absorption rate (SAR) value is designed for wearable application and ISM band biomedical applications. Here, dual-band microstrip antenna is printed on denim jeans substrate and has total area of 52.42 × 48.35 × 1.6 mm3 with a full ground plane. The proposed dual-band patch antenna with slot loaded covers frequencies of 2.4 and 5.8 GHz (lower sub-band of 5G communication) with the return loss of − 19 and − 16 dB. The designed antenna deliberates excellent performance higher values which gain up to 4.8 dB and low SAR value 0.298946 W/kg at 5.8 GHz and 0.152577 W/kg at 2.4 GHz. This dual-band antenna provides great solution for ISM band biomedical applications for wireless health monitoring.
