Abstract:

Microwave Integrated Circuits play a vital role in the Medical field for sensing applications. Two hundred million people are affected globally by musculoskeletal diseases, a substantial healthcare burden and one of the most costly diseases. Our proposed design is dedicated to the Bone Density Measurement Analysis (BDAS) RF system. This paper investigates the development of a directional - Branch Line Coupler with Defected Ground Structure (DGS) to differentiate between transmitted and reflected signals in the split ring resonator (SRR) sensor for Bone Density Measurement Analysis using the HFSS V13 design tool. The Coupler operates within the range of 2 GHz - 3 GHz frequency band with a high directivity of 55 dB. The proposed design is compared with a conventional branch-line coupler, and S-Parameters are calculated. The design is optimized in HFSS to meet the required specifications.
