Abstract

In this study, the design of a 2X2 MIMO microstrip antenna was proposed for LTE and 5G Sub-6GHz applications. The antenna is designed to have a wide bandwidth operating in the frequency range of 2300 MHz to 3600 MHz. The antenna material uses FR4 substrate which has a dielectric constant of 4.6 and a thickness of 1.6 mm. To achieve a wide bandwidth, the ground length is cut. Meanwhile, to achieve the resonant frequency using the square slot method on the radiator element. Antenna design begins with designing a single element shape, then designing a 2x2 MIMO antenna. The results of the MIMO2x2 antenna simulation show that the reflection coefficient and isolation coefficient of each antenna are below -10 dB. The results of the reflection coefficient of each antenna show that the bandwidth achieved is more than 2 GHz. At a frequency of 2300 MHz, the lowest gain is 2.98 dBi, while the highest gain is 3.10 dBi. The lowest and highest gains at a frequency of 3600 MHz are 3.83 dBi and 3.87 dBi. Overall, this antenna has achieved the desired goal, which is to have a wide bandwidth and be able to operate on LTE and 5G applications.

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%.

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

Abstract

This study proposes a microstrip array antenna with frequency at of 2.3 GHz – 2.5 GHz for various applications, with smaller antena dimensions. The microstrip antenna designed in this study uses a rectangular patch consisting of two patch elements arranged in a linear array. The type of substrate used is FR-4 with a dielectric constant (εr) = 4.3 and a substrate thickness (h) = 1.6 mm. The feeding technique used is indirect feeding using a microstrip line feed. To increase the bandwidth, the antennas are arranged in an array with 50 ohm and 100 ohm microstrip lines. The simulated antenna parameters are return loss value -10 dB, VSWR 2, and gain value. The simulation results of the two-element array design with a substrate size of 123 mm x 65 mm obtained a return loss value of -27.99 dB at a frequency of 2300 MHz, -15.16 dB at a frequency of 2400 MHz, and -29.29 dB. The bandwidth generated in this study is 460 MHz or an increase of up to 283.3% when compared to a 2x1 antenna array without slit. Furthermore, the addition of slits succeeded in reducing the dimensions of 34.43% compared to 2x1 antenna arrays without slits. This antenna is very useful as a wireless communication receiving antena.
