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

5G mobile communication technology has attracted much attention in the past three years. However, the development of antennas that can cover three types of 5G bands at once has not been studied. This paper proposes an antenna covering the three frequency bands of 2.3 GHz, 3.5 GHz, and 26 GHz for 5G communication. The proposed antenna uses a microstrip patch design with 50-ohm inset feeding. FDTD mathematical analysis through simulation has been carried out and confirmed that the proposed antenna meets the required specifications in 5G technology. The simulation result shows that the proposed antenna has a good reflection coefficient in the target frequencies of -22.6 dB, -28.26 dB, and -22.48 dB, respectively.

Abstract

The capability improvement of a telecommunications device influences the performance aspect of the device. In order to access the signal source, repeaters are required to reach signal to subscribers or improvements to the user's device itself that are able to reach signals that are far away. One of the telecommunications devices on the user side includes a low noise amplifier (LNA) which is useful for strengthening the signals and reducing the noise level received. This equipment supports to stay within reach of small signals received by users in areas with less signal. In this research, LNA is discussed specifically, especially increasing LNA gain and impedance matching methods through resonator modification. The LNA is designed using a two-stage cascading method which has high gain and low reflection factor. The simulation results show that the proposed LNA design succeeded in obtaining a gain of 31.6 dB where the stability and noise figure values obtained 3.79 dB and I.87 dB respectively. The T-Matching stub method used to adjust input and output impedance also succeeded in having a low reflection coefficient. At a frequency of 1575 MHz, the input and output reflection coefficients were obtained -70.5 dB and 56.2 dB. LNA design is divided into three steps, such as LNA bias design, single-stage LNA and cascaded connected two-stage LNA. The simulation results show that the LNA design meets the agreement with the desired target specifications.

Abstract

Perubahan pola hidup masyarakat yang cenderung praktis dan instan, di mana kenyamanan dan kecepatan menjadi prioritas, memberi dampak pada peningkatan kebutuhan jasa laundry sebagai solusi bagi masyarakat yang malas mencuci pakaian secara mandiri. Fenomena menjamurnya bisnis laundry sebagai konsekuensi langsung dari pola hidup ini telah membawa dampak besar pada permintaan cairan pembersih pakaian dalam skala besar. Keadaan ini menimbulkan tantangan bagi UMKM yang memproduksi cairan pembersih, dimana seringkali menghadapi keterbatasan dalam memenuhi permintaan yang meningkat pesat. Sejalan dengan dinamika tersebut, penelitian ini bertujuan untuk merancang alat produksi cairan pembersih yang dapat dipindahkan secara mudah serta memiliki konsistensi dalam hal pengemasan. Proses penelitian dilakukan mulai dari perancangan, pembuatan alat, dan pengujian alat. Dari hasil ujicoba diketahui bahwa setiap bagian sistem telah lolos uji dan mekanisme produksi antara satu bagian dengan bagian lain dapat bekerja dengan normal dan terukur.

Abstract

Penelitian ini mengajukan perancangan antena yang mampu beroperasi di dua frekuensi pada aplikasi 5G spectrum mid-band, yaitu frekuensi 2,6 GHz dan 3,5 GHz. Material yang digunakan pada perancangan berupa substrat RT/Duroid 5880 yang memiliki ketebalan 1,575 mm dan nilai konstanta dielektrik 2,2. Metode yang digunakan untuk mencapai dual-band frekuensi yaitu teknik inset-fed yang tidak simetris yang terletak pada sisi saluran pencatu. Selain itu, penelitian ini juga mengajukan metode antena susun (array) untuk meningkatkan gain antena. Perancangan dimulai dengan merancangan bentuk patch persegi panjang dengan inset-fed yang simetris, kemudian dimodifikasi dalam bentuk yang tidak simetris. Selanjutnya, patch inset-fed yang tidak simetris disusun menjadi elemen array 2x2. Hasil simulasi menujukan antena dengan menggunakan metode inset-fed mampu menghasilkan dua frekuensi resonan. Sementara itu, gain antena array yang dihasilkan pada frekuensi 2,6 GHz bernilai 10, 6 dBi dan pada frekuensi 3,5 GHz bernilai 13,1 dBi. Hasil tersebut menunjukan metode yang diajukan pada penelitian ini terbukti mampu menghasilkan dual-band frekuensi dan memiliki gain yang tinggi, sehingga mampu diaplikasi pada spectrum mid-band 5G.

Abstract

Using various new materials in current technological developments, besides providing opportunities for better product development, can also open research opportunities in the world of materials. In the last decade, magneto-dielectric materials have been extensively researched for use in various applications in the high-frequency spectrum. Before it can be implemented as a material that can be used widely, its characteristics must be identified first. This paper proposes the process of characterizing the electrical and magnetic properties of the high-frequency spectrum. Mathematical analysis carried out through simulations has identified the electrical and magnetic properties of the magneto-dielectric material so that the permittivity, permeability, and losses of both dielectric and magnetic can be determined. Based on the analysis results of several magneto-dielectric samples, the permittivity, permeability, and losses are directly proportional to the composition of magnetite (Fe3O4) in the magneto-dielectric material. With these results, the use of magneto-dielectric materials can be increasingly adapted to the electromagnetic properties they have.

Abstract

Indonesia will become a net importer if it runs out of oil and gas reserves within the next 11 to 12 years if no alternative energy sources are developed. Therefore, there is a need to utilize alternative energy that is not dependent on oil or gas. One alternative energy is using solar light energy. This research designed a device that can convert the energy of sunlight into electrical energy and automatically store electrical energy in a battery with PWM (Pulse Width Modulation) so that it can be used as alternative energy, and help reduce the consumption of electricity from PLN. The battery used 12V 80Ah and a solar panel module 50W for energy storage and system resources. The research results show that systems can automatically charge energy using sunlight and turn the lights to 7W. Using the charging system automatically uses PWM to reduce the risk of damage to the battery because, in the charging process, battery conditions will be monitored. The maximum power generated from solar panel modules used is 35.57 W.
