Feasibility Analysis Of Bone Abnormality Diagnosis Based On Microwave Technology

This paper studies the feasibility of monitoring bone abnormalities using microwave measurements. We design a compact T-shape dipole antenna with $30 mm \times 30mm$. Sixteen antennas are used to surround the limb model in simulation. S-parameters are acquired by taking one in turn as the transmitter and the rest as the receiver. We obtained a set of comparison diagrams with both 2-D and 3-D numerical simulations. In order to have a better analysis for low amplitude signals, the relative change rate of 3-D and 2-D simulations are calculated. We find the most changed location through relative change rate and analyze the reason for the change. Preliminary results verify the feasibility of microwave detection of bone abnormalities.
