This work is to design a microstrip ring resonator (MRR) sensor that has the capability to measure the Q-factor and dielectric constant of the selective material. The first step is to design a basic microstrip ring resonator, called Design A. Then the enhancement coupling method of microstrip ring resonator, called Design B is done to improve the performance of the return loss and to ensure the wanted resonant frequency. The performance of this enhancement coupling method of microstrip ring resonator shows of the resonant frequency at 2.096 GHz with the return loss of – 22.063 dB and bandwidth of 10 MHz in between of 2.090 GHz and 2.100 GHz. Using this return loss and the resonant frequency, the Q-factor can be calculated. Then, this microstrip ring resonator with the selective material under test (MUT) or namely as the sample are simulated and compared with the air (εr = 1) as the reference sample. The MUT that apply in this work are Roger 5880 (εr = 2.2), Roger 4350 (εr = 3.48) and FR-4 (εr = 4.4) while the measured dielectric constant that captured are 0.958, 2.163, 3.437, 4.360, respectively.

Microstrip ring resonator (MRR) sensor was modeled by simple equivalent lumped element circuits in free space based on simulation data obtained from Microwave Office (AWR) simulator and comparison was made with the measurements using the E5071C Network Analyzer. The calculated reflection coefficient, |G| and complex input impedanceZinusing lumped element model were compared with the measurements results. Both results showed well agreement with a little discrepancy, basically due to imperfect soldering. The MRR was designed to have operating frequencies between 0.5 GHz and 4.5 GHz. The maximum surrounding of magnetic field,Hϕis within 15 A/m in free space.
