Abstract

Saat ini, penyebaran Coronavirus Disease (COVID-19) semakin hari semakin menyebar ke seluruh wilayah Indonesia, termasuk Kota Surabaya. Data per 7 Mei 2020 di Kota Surabaya, total ODP (Orang Dalam Pemantau) kumulatif sekitar 2.881 orang, total PDP (Pasien Dalam Pengawasan) kumulatif sekitar 1.461 orang, kumulatif orang terkena COVID-19 sekitar 592 orang. Kumulatif data orang sembuh dari COVID-19 sekitar 91 orang dan kumulatif data orang meninggal karena COVID-19 sekitar 78 orang. Jumlah data tersebut semakin meningkat dengan adanya ditemukan klaster baru COVID-19 dari PT HM Sampoerna, Rungkut 2 Surabaya. Salah satu upaya dalam mencegah penyebaran COVID-19 adalah tetap tinggal di rumah dan menggunakan masker serta sarung tangan bila ada aktivitas di luar rumah. Saat ini, masker dibutuhkan semua orang, termasuk penyandang tunarungu. Permasalahan yang terjadi adalah masker tersebut menutup bagian bibir, dikarenakan bagian bibir tersebut digunakan penyandang tunarungu dalam berkomunikasi. Mitra dari kegiatan pengabdian masyarakat adalah komunitas penyandang tunarungu yang berada di Kota Surabaya. Metode yang digunakan tim pengabdian adalah membuatkan masker khusus bagi penyandang tunarungu dengan memodifikasi masker bagian bibir, sehingga dapat terlihat dalam berkomunikasi. Hasil dari kegiatan pengabdian adalah tim pengabdian membagikan masker secara gratis bagi komunitas penyandang tunarungu di Kota Surabaya

Abstract

This study discusses the design of the MIMO microstrip antenna which is implemented in a 5G communication system that works on the N40 frequency band (2.3-2.4 GHz) with the center frequency of 2.35 GHz. The parameters that are unique of this antenna is focusing on the mutual coupling and correlation of MIMO antennas. The MIMO configuration was chosen because it can meet the high data transmission needs of 5G communication systems. The antenna is composed of a square patch with a microstrip insert feed-line technique. Then, the substrate uses FR-4 material, with a dielectric constant value of 4.3. After the design of a single element antenna that works according to the criteria is obtained, then the antenna is arranged into a configuration of 4 parallel elements, a 2×2 MIMO configuration with uniform polarization, and a 2×2 MIMO configuration with non-uniform polarization. After the design process, the antenna design is fabricated and then measured using a Vector Network Analyzer (VNA). The analysed antenna parameters are return loss, mutual coupling, Voltage Standing Wave Ratio (VSWR), bandwidth, and radiation pattern. From the element measurement results, it is found that the return loss is -11.24 dB and the bandwidth is 70 MHz at the center frequency of 2.35 GHz. As for the analysis of mutual coupling between elements, the best results were obtained from the MIMO configuration of 2×2 non-uniform polarization with values -20 dB for all elements. The antenna measurement results obtained indicate a similarity with the simulation results. This result is suitable for MIMO applications that require very low mutual coupling and correlation between elements.

Abstract

In this paper, a thinned linear array with Cavity backed U-slot Patch has been investigated using the Genetic Algorithm to minimize peak sidelobe level and the number of antenna elements. One of the essential steps in the Genetic Algorithm method is a crossover, which uses the Paired Top Ten and Combined Top Five rules applied to the Cavity backed U-slot Patch antenna. The peak sidelobe level value is -18.63 dB with a array filling of 63.33% at the broadside angle using Combined Top Five rules. In Paired Top Ten, the peak sidelobe level value is -19.48 dB with a array filling of 70%. The two methods are still better as compared to a dense array. This study is essential in the development of radar technologies since it needs a low sidelobe level.
