P Penelitian ini membahas perancangan, optimasi, pabrikasi, dan validasi antena mikrostrip array 1×2 element berbasis teknik miniaturisasi peripheral-slit untuk aplikasi long range (lora) pada pita frekuensi 920–923 mhz. antena dirancang menggunakan substrat fr-4 epoxy dan dikembangkan dari desain single element, peripheral-slit, miniaturisasi, hingga konfigurasi array 1×2 element. proses simulasi dilakukan menggunakan awr dan hfss, sedangkan hasil pabrikasi diuji menggunakan vector network analyzer (vna). hasil simulasi awr menghasilkan nilai s11 sebesar −32,25 db, bandwidth 37 mhz, vswr 1,05, dan gain 6,87 dbi. sementara itu, hasil simulasi hfss menghasilkan nilai s11 sebesar −27,94 db, bandwidth 20 mhz, vswr 1,08, impedansi mendekati 50 Ω, dan pola radiasi terarah. setelah dilakukan pabrikasi dan tuning, hasil pengukuran menunjukkan nilai s11 sebesar −32,62 db, bandwidth 20 mhz, vswr 1,08, dan frekuensi resonansi sebesar 927 mhz. berdasarkan perbandingan antara simulasi hfss dan hasil pengukuran, diperoleh deviasi s11 sebesar 4,68 db dengan tingkat kesesuaian 83,25%, deviasi bandwidth sebesar 0 mhz dengan tingkat kesesuaian 100%, dan deviasi vswr sebesar 0 dengan tingkat kesesuaian 100%. namun, frekuensi resonansi hasil pabrikasi mengalami pergeseran sekitar 6 mhz dari hasil simulasi dan belum tepat berada pada pita target 920–923 mhz. selain itu, apabila mengacu pada target bandwidth sebesar ≥50 mhz, maka bandwidth hasil pabrikasi sebesar 20 mhz belum memenuhi target tersebut. meskipun demikian, rentang frekuensi 920–923 mhz masih berada dalam cakupan bandwidth hasil pengukuran dengan batas s11 ≤ −10 db, sehingga antena masih memiliki pencocokan impedansi yang baik pada rentang kerja lora. hasil penelitian ini menunjukkan bahwa antena yang dirancang memiliki performa s11 dan vswr yang baik, namun masih memerlukan penyempurnaan dimensi pabrikasi agar frekuensi resonansi dan bandwidth dapat lebih sesuai dengan target perancangan.
T This study discusses the design, optimization, fabrication, and validation of a 1×2 element microstrip array antenna based on the peripheral-slit miniaturization technique for long range (lora) applications in the 920–923 mhz frequency band. the antenna was designed using an fr-4 epoxy substrate and developed through several stages, starting from a single-element design, followed by the application of the peripheral-slit technique, miniaturization, and finally the 1×2 element array configuration. the simulation process was carried out using awr and hfss, while the fabricated prototype was measured using a vector network analyzer (vna). the awr simulation results showed an s11 value of −32.25 db, a bandwidth of 37 mhz, a vswr of 1.05, and a gain of 6.87 dbi. meanwhile, the hfss simulation results produced an s11 value of −27.94 db, a bandwidth of 20 mhz, a vswr of 1.08, an impedance close to 50 Ω, and a directional radiation pattern. after fabrication and tuning, the measurement results showed an s11 value of −32.62 db, a bandwidth of 20 mhz, a vswr of 1.08, and a resonant frequency of 927 mhz. based on the comparison between the hfss simulation and measurement results, the s11 deviation was 4.68 db with an agreement level of 83.25%. the bandwidth deviation was 0 mhz with an agreement level of 100%, and the vswr deviation was 0 with an agreement level of 100%. however, the resonant frequency of the fabricated antenna shifted by approximately 6 mhz from the simulation result and was not exactly within the target frequency band of 920–923 mhz. in addition, referring to the bandwidth target of ≥50 mhz, the measured bandwidth of 20 mhz has not yet met the specified target. nevertheless, the 920–923 mhz frequency range is still covered within the measured bandwidth based on the s11 ≤ −10 db criterion, indicating that the antenna still provides good impedance matching within the lora operating range. the results of this study indicate that the proposed antenna has good s11 and vswr performance. however, further dimensional refinement in the fabrication process is required so that the resonant frequency and bandwidth can better meet the design targets.
