An antenna-based sensor with novel combinational design of metamaterial and transmission line are proposed for the applications of biosensors. Working at 1.6 GHz resonant frequency, our design aims to reduce the size of antenna biosensor by applying metamaterial structure. The active sensing area of antenna was optimized based on the distribution of electrical field to measure the permittivity and loss tangent of sample by the scattering parameters. The resonant frequency shifts from 1.69 GHz to...
