Complementary Split Ring Resonator

Material characterization method based on radio frequency and microwave measurements is highly demanded. The dielectric properties are very important for electronic circuit design, food industry, and medicine and health care. In this work, a complementary split-ring resonator (CSRR)-based sensor employed in the ground plane is proposed for dielectric measurement. This method enables the determination of both relative permittivity and relative permeability at the same time as well as simple sample preparation process. This project focuses on the design, simulation and the prediction formulae of the CSRR. This CSRR is resonating at 2.477 GHz with a quality factor of 128.91 in unloaded condition. Basically, there are shifting in the resonance frequency and the change of the quality factor when dielectric material is placed at the sensing area in separate zones. Four prediction formulas are proposed, which they are depend on the dielectric constant, real permeability, normalized resonance frequency, inverse normalized quality factor, electric loss tangent and magnetic loss tangent of the materials. These formulae are used to measure the permittivity and permeability of FR-4, Polyimide, and self-defined material. Based on the comparison, the percentage error between calculated result and reference data are 10% and 4.1% for electric and magnetic loss tangent respectively. The maximum percentage error in dielectric constant and real permeability are 4.5% and 4.29% respectively. Based on the percentage of error, it is convincing that the prediction formulas are reliable for dielectric measurement. Future work of this project should focus on verification of its actual performance through experimental measurement.

Pada penelitian ini dilakukan perancangan antena mikrostrip dengan menggunakan metode split ring resonator (SRR) untuk aplikasi pada frekuensi L-Band. Antena ini mempunyai dimensi substrat 90 mm x 50 mm dengan panjang patch 60 mm dan lebar patch 44 mm. Desain antena menggunakan material FR4-Epoxy dengan spesifikasi konstanta dielektrik 4,6 dengan ketebalan 1,6 mm dan dielectric loss tangent 0,02. Pada penelitian ini, parameter yang mengalami perubahan signifikan adalah lebar patch SRR, gap SRR, dan posisi SRR pada ground plane. Desain patch SRR dengan nilai sepertiga panjang gelombang pada frekuensi 1,5 GHz memenuhi karakteristik dari frekuensi L-Band. Berdasarkan hasil simulasi, antena menghasilkan bandwidth (< -10 dB) sebesar 1,2466 GHz dengan rentang frekuensi 988,25 MHz sampai 2,2349 GHz. Nilai return loss simulasi adalah -36,89 dB. Pada rentang 1 GHz sampai 2 GHz, gain tertinggi berada pada frekuensi 2 GHz dengan nilai 3,5 dBi. Sedangkan gain terendah adalah 1,21 dBi, yaitu pada frekuensi 1,050 GHz. Secara keseluruhan, desain antena ini telah mencapai performa kinerja yang lebih baik melalui modifikasi pada patch SRR.
