| Summary: | The interdigital sensor has been implemented in various field of applications
such as microwave device, chemical sensor and biological sensor. This work
describes the design and fabrication of an interdigital sensor (IDS) design
that has the potential of estimating blood glucose levels using capacitive
measurements. The IDS was first designed using theoretical equations and
later was optimized by using CST Microwave Studio®. The electrode widths
of the sensor were varied from 0.5mm to 0.7mm and the S11 reflection
characteristics were simulated. Upon completion of simulations, the sensor
was fabricated using copper clad FR4 boards. The fabricated sensors were
measured using a vector network analyzer (VNA) and produced resonance
frequencies of 2.02, 2.11 and 2.14 GHz. The highest Q obtained was 11.72
from the 2.11 GHz sensor |
