Abstract

The Fifth Generation (5G) communication system promises high data transfer rates. It requires an antenna that can operate with gain and bandwidth at 3.4 – 3.6 GHz frequency range which complies with 5G frequency regulation. This study proposes an optimized 2x1 element array microstrip antenna using inset and slit techniques. The antenna is designed to operate at 3.5 GHz for 5G communication systems. The array method is used to increase the gain value, while inset and slit techniques are used to reduce the reflection coefficient (S11). From the design and simulation results, the reflection coefficient value is – 24 dB and the bandwidth is 360 MHz (3.32 GHz -3.68 GHz), or 10.28%, at a frequency of 3.5 GHz. The use of the array method worked in increasing the gain by 66.67% and the bandwidth by 70.43%, compared to single-element antennas.  Sistem komunikasi Generasi Kelima (5G) menjanjikan kecepatan transfer data yang sangat tinggi sehingga memerlukan antena yang dapat bekerja dengan penguatan dan bandwidth pada rentang frekuensi 3,4 hingga 3,6 GHz yang sesuai dengan regulasi frekuensi 5G. Penelitian ini mengusulkan desain antena mikrostrip array 2x1 elemen yang dioptimalisasi menggunakan teknik inset dan slit. Antena dirancang untuk bekerja pada frekuensi kerja 3.5 GHz untuk sistem komunikasi 5G. Metode array digunakan untuk meningkatkan nilai gain dari antena, sedangkan teknik inset  dan slit digunakan untuk mereduksi nilai koefisien refleksi (S11) dari antena yang diusulkan. Dari hasil perancangan dan simulasi didapatkan nilai koefisien refleksi – 24 dB dan bandwidth 360 MHz (3,32 GHz hingga 3,68 GHz), atau 10,28%, pada frekuensi 3,5 GHz. Penggunaan metode array berhasil meningkatkan gain sebesar 66,67% dan bandwidth sebesar 70,43% dibandingkan dengan antena single element.

Abstract

The 5th generation (5G) is expected to meet the needs of telecommunications technology in the future. According to the Research Team of the SDPPI Research and Development Center for Resources and Equipment for Post and Information Technology, the Ministry of Communications and Informatics has several advantages, namely: high data rate, reduced latency, increased capacity of connected devices, and more energy-efficient. Microstrip antenna for wireless communication has several drawbacks such as low gain, poor directionality, and multipath fading. Selection of multi-antenna by applying massive MIMO on eMBB to avoid multipath fading, provide gain, and greater capacity to serve many users simultaneously. In Indonesia, based on the Indonesian Radio Frequency Spectrum Table, the priority is in the 3.4-4.2 GHz frequency range. The substrate used is RT Duroid 5880 with a dielectric constant of 2.2. The patch used is rectangular with slots to increase the antenna bandwidth. In this study, the performance of the MIMO antenna has reached the target, where the antenna isolation loss is -63.16 dB so that the correlation coefficient value is 3.97 x 10-7, and the diversity gain is 10 dB.  Generasi kelima (5G) diharapkan dapat memenuhi kebutuhan teknologi telekomunikasi di masa depan. Beberapa kelebihan yang dimiliki teknologi Generasi Kelima (5G), menurut Tim Peniliti Puslitbang SDPPI (Pusat Penelitian dan Pengembangan Sumber Daya dan Perangkat Pos dan Informatika) Kemkominfo, yaitu: data rate tinggi, mengurangi latency, meningkatkan kapasitas perangkat terhubung, dan lebih hemat energi. Antena microstrip memiliki beberapa kekurangan, yaitu gain yang rendah, keterarahan yang kurang baik, dan multipath fading. Pemilihan multi-antena dengan cara mengaplikasikan massive MIMO pada eMBB digunakan untuk menghindari multipath fading, memberikan gain, dan kapasitas yang lebih besar untuk melayani user yang banyak secara bersamaan. Di Indonesia, berdasarkan Tabel Spektrum Frekuensi Radio Indonesia, diutamakan dalam rentang frekuensi 3,4—4,2 GHz. Substrat yang digunakan yaitu RT Duroid 5880 dengan konstanta dielektrik 2,2. Patch yang digunakan adalah rectangular dengan penambahan slot pada patch tersebut untuk meningkatkan bandwidth antena. Pada penelitian ini kinerja antena MIMO yang didapatkan telah mencapai target, di mana besar isolation loss antena sebesar -63,16 dB sehingga didapatkan nilai koefisien korelasi sebesar 3,97 x 10-7 , dan diversity gain sebesar 10 dB.

Abstract

In this research, microstrip antenna design is carried out using the inset and slot methods. This research proposes a microstrip antenna with three working frequencies, namely 1.3 GHz for radar applications and 1.8 and 2.6 GHz for 4G LTE applications. To fulfill the proposal, the type of substrate used is FR4 with a value of 4.3 for ɛr and 1.6 millimeters for h. This research resulted in the initial design of a dual-band microstrip antenna that works at frequencies of 1.8 and 2.6 GHz for 4G LTE applications. Furthermore, the proposed T-slot and U-slot methods are added to generate a resonant frequency at 1.3 GHz for radar applications. The return loss results in the inset method are -20.76 dB at 1.79 GHz and -20.20 dB at 2.60 GHz. The addition of T-slot with fixed inset parameters results in -11.66 dB at 1.37 GHz, -17.31 dB at 1.95 GHz, and -20.56 dB at 2.59 GHz, then the addition of inverted U-slot results in -33.49 dB at 1.30 GHz, -22.13 dB at 1.80 GHz and -21.36 dB at 2.59 GHz. The simulation results obtained bandwidth of the working frequency at the third iteration are 1.04%, 2.22% and 1.18%. This research is simulated and designed with Simulator software. This research can be recommended as a radar and LTE communication system.
