Abstract

Wearable antenna has an important role in WBAN (Wireless Body Area Network) as the main component that supports on-body communication. This study focuses on the characterization of Material Under Test (MUT) from Indonesian traditional batik material using the CSRR (Complementary split ring resonator) sensor extraction method. The frequency response and magnitude of S21 are used to extract the relative permittivity and loss tangent of the material. From all the responses that appear, a simulation and measurement of wearable antennas is carried out with a working frequency of 2.4. GHz. The antenna with the most similar simulation and measurement results is then selected as a candidate for relative permittivity and loss tangent of the material. From all the 6 frequency responses that emerged from CSRR sensor measurements, the relative permittivity value of 2.083 and the loss tangent of 0.144 achieved a good similarity between the measurement and simulation with an accuracy rate of 99.17%. The final design of the proposed wearable antenna is also validated to transmit heart rate data using the ESP32 microcontroller to the internet using a 2.4 GHz frequency Wifi access point. Key Words: Wearable antenna, extraction of material characteristics, wireless body area network (WBAN), CSRR, material under test, vital signs

Abstract

Antena mikrostrip merupakan perangkat komunikasi wireless berdimensi kecil namun memiliki kinerja yangmendukung pengimplementasian teknologi 5G. Antenna mikrostip memiliki bentuk seperti lempengan tipisdengan frekuensi kerja yang ditentukan berdasarkan dimensi antena tersebut. Namun, dibalik kelebihan yangdimiliki antena ini masih terdapat kekurangan seperti gain dan efisiensi yang rendah, bandwidth sempit, dangelombang permukaan yang mampu merusak pola radiasi. Antena mikrostrip yang bekerja dengan frekuensi5G atau frekuensi 3,5 GHz memiliki pancaran radiasi yang berbahaya bagi seluruh tubuh. Oleh karena ituditambahkan struktur material Elegtromagnetic Band Gap (EBG) yang berbentuk mushroom-like. Penggunaanstruktur ini dapat meningkatkan efisiensi, pola radiasi yang baik, dan dapat mengurangi efek radiasi pada tubuh,nilai Spesfic Absorption Rate (SAR) yang harus dimiliki yaitu < 1,6. Pengujian dilakukan dengan dua kondisi, yangpertama yaitu simulasi antena konvensional terhadap phantom tangan dan yang kedua adalah simulasi antenadengan penambahan struktur EBG terhadap phantom tangan. Simulasi yang pertama menghasilkan nilai SARsebesar 1,9484 W/Kg. Sedangkan simulasi yang kedua menghasilkan nilai SAR sebesar 0,9059 W/Kg. Sehinggadidapat kesimpulan bahwa penambahan struktur EBG unitcell dapat mengurangi nilai SAR hingga mencapai46,67%.
