Abstract

Along with the times, communication technology has developed so that it is currently included in the Fifth Generation (5G) Communication System. The 5G communication system is divided into three frequency categories, namely low band, middle band and high band. One of the important devices in the telecommunications sector is the antenna. Antenna serves to send and receive electromagnetic signals at a certain working frequency. Currently, antennas have been completely integrated into the needs of modern society. One type of antenna that can support the needs of today's technology is a microstrip antenna. This antenna has several advantages, especially in its antenna compact design, low profile configuration and affordable manufacturing costs. In this article, a microstrip antenna is designed with the spiral labyrinth  method that works at a frequency of 3.5 GHz for 5G communication system. Propsosed antena designed using RT Duroid R5880 with dielectric constant ( ) 2.2, dielectric loss (loss tan) 0.0009 and thickness (h) 1.57 mm. The simulation results show the reflection coefficient -29.58 dB, VSWR 1.069, gain 6.432 dB at frequency of 3.5 GHz . Spiral labyrinth  has been succesfully reduced patch antenna and enclosure until 22.5%  and 24.8%, respectively.

Abstract

The fifth generation (5G) technology offers high speed communication systems and requires a multi input and multi output (Multiple Input Multiple Output / MIMO) antenna system to increase customer capacity. This research proposes a microstrip antenna design for a fifth-generation (5G) communication system that works at a frequency of 3.5 GHz. The antenna was designed using the RT-Duroid R5880 substrate type with dielectric constant (εr) = 2.2, thickness (h) = 1.57 mm and loss tan (tan α) = 0.0009. To produce optimal parameter, the antenna is optimized using slit on the edge with a total of 2 pairs. The addition of an inset aims to reduce the reflection coefficient  of the proposed antenna. From the simulation results, the reflection coefficient value is -25 dB at a frequency of 3.5 GHz with a bandwidth of 220 MHz. The gain of the proposed antenna is 10 dB at a frequency of 3.5 GHz. The isolation coefficient obtained is -70 dB with a distance between (d) = 43 mm. The application of the MIMO antenna increases the gain by 49.52% compared to the single element microstrip antenna.

Abstract

The development of cellular technology has now entered the 5th generation (5G), this 5th generation provides 3 types of services, eMBB (enhanced Mobile BroadBand), URLLC (Ultra-Reliable and Low-Latency Communications) and mMTC (massive Machine Type of Communications).  One of the important devices in 5G technology is an antenna device which is able to support these 3 services. 5G technology requires an antenna that has high performance. There are various types of antennas, one of which is a microstrip antenna. Microstrip antenna is one of the most widely used antennas in telecommunications because of its light mass, small dimensions and easy fabrication. There are various ways or methods that can be done to overcome the narrow bandwidth of microstrip antennas, by increasing the thickness of the substrate, using parasitic elements, reducing the value of the dielectric constant, adding inserts to the feeder, or by modifying the patch by adding slots on the patch antenna. In this study to improve the performance value of the microstrip antenna, the researchers discussed increasing the reflection coefficient by adding X Slots to a microstrip antenna with a working frequency of 3.5 GHz for 5G communication. The results of this study showed an increase in the reflection coefficient of 67%, and an increase in bandwidth of 5%.

Abstract

AbstrakSistem komunikasi generasi kelima (5G) telah diperkenalkan pada tahun 2018 dan memiliki kelebihan antara lain kecepatan transfer data yang tinggi serta bandwidth yang sangat lebar. Berdasarkan regulasi yang ditetapkan oleh frekuensi kerja yang digunakan untuk sistem komunikasi generasi kelima (5G) terbagi menjadi beberapa band yaitu untuk high band 28 GHz, middle band 15 GHz dan low band 3,5 GHz. Penelitian ini akan melakukan optimasi bandwidth . Penelitian ini mengusulkan optimasi bandwidth desain antena mikrostrip persegi panjang dengan metode slit, dan elemen parasitik pada frekuensi kerja 15 GHz untuk komunikasi 5G. Metode celah digunakan untuk meningkatkan nilaireturn loss sedangkan element parasitik digunakan untuk meningkatkan bandwidth dari antena yang diusulkan. Tujuan dari optimasi yang dilakukan untuk mendapatkan desain antena yang memiliki bandwidth yang lebar dan bekerja pada frekuensi 15 GHz dikarenakan pada penelitian sebelumnya optimasi bandwidth yang dilakukan hanya kurang dari 20%. Dari proses simulasi didapatkan peningkatan bandwidth sebesar 169,075% dan Return Loss meningkat sebesar 48,65%. Penelitian ini dapat direkomendasikan sebagai disain antena penerima pada sistem komunikasi generasi kelima (5G) dimana penambahan celah dan elemen parasitik dapat mengoptimasi bandwidth .Kata Kunci: antena, mikrostrip, slit, peningkatan bandwidth, elemen parasitik
