Design of A Patch Antenna with Three Bands for Vital Signs Monitoring Devices

Abstract

Vital signs monitoring is an essential part of protecting human well-being because it represents an indicator of any health abnormality. For this reason, a patch antenna of three bands is proposed in this article. This antenna is made up of two sides of copper with a thickness of 0.035 mm, isolated by a layer of FR-4 substrate material with a thickness of 1.6 mm, and a dielectric constant of 4.3. The antenna showed three resonance frequencies of (3.90) GHz, (6.38) GHz, and (8.64) GHz, respectively. The proposed antenna design was simulated by CST microwave studio software. Since The suggested antenna works at VHF and UHF bands, it is a probable candidate to be utilized in the fields of WBC image enhancement, biomedical sensing applications, and biomedical temperature monitoring.
