Abstract

A uniform and homogeneous 4X4 array-based metasurface-backed polarization diversified microstrip patch antenna (MPA) has been proposed to study the characteristics of human physiology and blood composition in at least three different frequencies [viz: GSM (2.27 GHz); WLAN (5.2 GHz); and X-band (8.78 GHz)] when used as an invasive or non-invasive sensor. It is capable of transceiving the information over the same commonly used frequency band(s). The proposed polarization diversified antenna can accurately characterize the physiological changes of the behavior of biosamples / biofluids occasioned by their height dielectric constant, and conductivity variations with three different frequencies yielding S11 <-10 dB.
