Metasurface-Backed Polarization-Diversified Microstrip Patch Antenna for Biomedical Multi-communication Applications
摘要
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 noninvasive 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.
