Biologically-inspired vascular antenna reconfiguration mechanism

Electronics Letters, 2011
A biologically-inspired fluidic network based on the human vascular system and transport of colloidal dispersions is proposed as an antenna reconfiguration mechanism. The impact of fluidic colloidal dispersion properties on the impedance behaviour is predicted. Trends in analytical, simulated and measured results show good agreement.
