Antena microstrip fed inset patch tertanam di permukaan planar dan kurva silindris diperkenalkan untuk digunakan dalam Body Area Networks (BAN). Antena ini dirancang sebagai wearable antena untuk jaringan nirkabel pada industrial, scientific and medical (ISM). Antena yang diusulkan terdiri dari baris microstrip 50 Ω feeding inset patch dicetak pada muka depan substrat dielektrik dan bagian persegi muka bawah. Antena planar diusulkan pada substrat silindris dengan jari-jari 2,5 cm, 5 cm, dan 7,5 cm yang masing-masing disesuaikan dengan ukuran pergelangan tangan manusia, humerus dan bahu tubuh manusia. Pemodelan dan evaluasi kinerja struktur silindris telah dilakukan dengan menggunakan perangkat lunak elektromagnetik CST Studio Suite 2009yang tersedia secara komersial. Hasil simulasi diperoleh rugi balik, distribusi arus, dan pola radiasi antena. Hasil menunjukkan bahwa antena konformal beresonansi pada frekuensi yang dirancang dengan karakteristik gain dan polamedan yang wajar.
Deskripsi Alternatif :Microstrip fed inset patch antennas embedded in planar and cylindrically curved surfaces are introduced to be used in Body Area Networks (BANs) presented. These antennas are designed as wearable antennas for industrial, scientific and medical (ISM) band wireless communication networking. The proposed antennas consist of 50 Ω microstrip line feeding inset patch printed on the front face of dielectric substrate and a rectangular ground plane on the bottom face. The proposed planar antenna is conformed on finite cylindrical substrates of radii 2.5, 5 and 7.5 cm corresponding approximately to the typical size of human wrist, humerus and shoulder of a human body respectively. Modeling and performance evaluation of the cylindrical structures has been carried out using the commercially available electromagnetic software CST Studio Suite2009. Simulation results, obtained for the return losses, current distribution, and radiation pattern of the antennas are presented. Furthermore, results show that the designed conformal antennas are resonating at the designed frequency with reasonable gain and field pattern characteristics.
