Abstract

This study compares the performance of conventional circular patch and modified 27-star patch microstrip antennas, both operating at 2.4 GHz. Microstrip antennas are commonly used for their small size, though they have limitations such as low bandwidth. This research aims to improve antenna performance through geometric modifications and analyze the performance of the two antennas. Simulation results show that the 27-star patch achieves better return loss (-37.05 dB vs -35.31 dB) and superior bandwidth, while the circular patch performs better in real-world bandwidth tests (>4.2 GHz vs >4GHz). The circular patch exhibits a omnidirectional radiation pattern with elliptical polarization, whereas the 27-star patch shows a omnidirectional pattern with linear polarization. This study highlights the significance of geometric modifications and fabrication precision in enhancing microstrip antenna performance.

Abstract

Wi-Fi (Wireless Fidelity) merupakan salah satu standar komunikasi nirkabel yang paling populer di pasaran. Teknologi ini banyak digunakan baik di perkantoran, kampus, kafe, dan tempat umum lainnya. Di Indonesia, untuk keperluan Wi-Fi sudah dialokasikan dalam ISM band pada frekuensi 2.4 GHz dan 5.8 GHz.Untuk membantu proses transimisi data biasanya menggunakan antena. Antena memiliki peran sebagai pengirim dan penerima gelombang elektromagnetik yang berisi informasi-informasi oleh pengguna. Perancangan antenna mikrostrip bintang 24 bertujuan untuk menemukan formula antenna microstrip yang dibutuhkan oleh teknologi Wi-Fi. Pada penelitian ini akan merancang antenna microstrip patch bintang 24 untuk Wi-Fi yang bekerja pada frekuensi 2.4 GHz dan 5.8 GHz. Perangkat lunak yang digunakan dalam merancang antenna yaitu CST Studio Suite 2021 dengan menggunakan bahan substrat FR-4. Dari hasil simulasi antenna patch bintang 24 2.4 GHz memiliki nilai return loss-26.78 dB, VSWR 1.09, bandwidth 520 MHz, gain 4.46 dBi, impedansi 55.08 ohm dan pola radiasi ke segala arah. Dari hasil simulasi antenna patch bintang 24 5.8 GHz memiliki nilai return loss -41.05 dB, VSWR 1.01, bandwidth 1820 MHz, gain 4.35 dBi, impedansi 50.89 ohm, dan pola radiasi ke segala arah. Dari hasil pengukuran antenna patch bintang 24 2.4 GHz memiliki nilai return loss -21.74 dB, VSWR 1.17, bandwidth 2960 MHz, gain 4.31 dBi, impedansi 58.92 ohm, dan pola radiasi ke segala arah. Dari hasil pengukuran antenna patch bintang 24 5.8 GHz memiliki nilai return loss-20.22 dB, VSWR 1.21, bandwidth 2640 MHz, gain 4.19 dBi, impedansi 60.79 ohm, dan pola radiasi ke segala arah. Antena patch bintang 24 2.4 GHz menunjukkan performa yang lebih baik untuk aplikasi jaringan Wi-Fi dibandingkan antenna patch bintang 24 5.8 GHz. Kata Kunci: Komunikasi Nirkabel, Wi-Fi, Antena microstrip patch bintang 24, Performansi antena

Abstract

Indonesia, as the largest archipelagic country in the world, with an area of 2 million square kilometers and consists of 17,500 islands, as well as a population of around 250 million people. Facing challenges in the development of telecommunications infrastructure, especially in remote areas, Indonesia faces difficulties in providing equitable telecommunications access, especially in remote areas. Although most villages and sub-districts have been covered by BTS signals, some still experience weak signal constraints or do not get a signal at all. Alternative solutions such as OpenBTS, an open-source software project, are becoming relevant in this context. OpenBTS can help address infrastructure challenges by providing telecommunications services such as phone calls and SMS at lower implementation costs. However, it should be noted that the use of OpenBTS can also face challenges such as delays in service, especially in Non-Line-of-Sight (NLOS) conditions.The purpose of this study is to design an OpenBTS telecommunication network using an Ubuntu 14.04.6-based USRP N210 device. Then improve the quality of use by optimizing the OpenBTS service and testing its reliability in various operational scenarios, including the use of SMS andphone call services.Keywords: GSM, OpenBTS, USRP, SMS, Telephone, Delay
