Inset-FED microstrip patch antenna for glucose detection using label-free microwave sensing mechanism

Vol. 30, nr 2

211--222

In this work, a real-time label-free microwave sensing mechanism for glucose concentration monitoring using a planar biosensor configured with an inset fed microstrip patch antenna has been demonstrated. A microstrip patch antenna with the resonating frequency of 1.45 GHz has been designed and is fabricated on the Flame Retardant (FR-4) substrate. Due to the intense electromagnetic field at the edges of the patch antenna, edge length has been used as the detecting area where the sample under test (SUT) interacts with the electromagnetic field. The Poly-Dimethyl-Siloxane (PDMS) with the trench in the centre has been employed as the sample holder. Here, the SUT is the glucose dissolved in DI (de-ionized) water with the concentration range of 0.2 to 0.6 g/mL. The dielectric constant dependency on the glucose concentration has been used as the distinguishing factor which results in a shift in the S-parameter. The experimentally measured RF parameters were observed closely which showed the shift in S11 magnitude from -40 to -15 dB and resonant frequency from 1.27 to 1.3 GHz w.r.t the SUT solution of 0.2 to 0.6 g/mL with linear regression coefficient of 0.881, and 0.983 respectively.

Aim of this work is to review and characterize methods and systems that are used to prevent onset and to slow down the progression of the late complications of diabetes. Two groups of methods and systems that might be used to prevent or to slow down the progression of the late complications of diabetes are characterized in this paper. Each of these two groups serves a different purpose. The first group is composed of the systems that facilitate a maintenance of strict metabolic control in diabetic patients, i.e. the systems which are used for monitoring and treatment of diabetes. The second group contains systems that are aimed at screening/monitoring or treatment of the risk factors or the early signs of the late complications. Obesity increases risk of diabetes and its complications. Thus, body mass monitoring and control systems are examples of the tools that belong to this group. Other examples include the diabetic retinopathy telescreening systems and the systems for monitoring of the diabetic foot syndrome.
