Abstract
Generasi kelima (5G) standar nirkabel secara signifikan meningkatkan kinerja sistem nirkabel dalam hal kecepatan data, kapasitas sistem dan konektivitas perangkat. Teknologi Massive MIMO memungkinkan untuk menggunakan array antena dengan beberapa ratus antena secara bersamaan pada waktu dan frekuensi yang sama sehingga spectral efficiency atau jumlah informasi yang ditransmisikan akan semakin meningkat. Hal tersebut dianggap sebagai salah satu teknologi yang paling menjanjikan untuk pengembangan jaringan broadband di masa depan.
Pada penelitian ini akan dilakukan proses perancangan elemen antena microstrip dan perancangan antena microstrip sub-array. Proses perancangan antena dimulai dengan menentukan parameter kinerja antena. Selanjutnya melakukan desain elemen tunggal antena microstrip, dilanjutkan proses pelebaran bandwidth dengan menggunakan teknik parasitic patch, kemudian perancangan antena microstrip sub-array.
Hasil simulasi diverifikasi dengan hasil pengukuran. Antena yang dibuat adalah antenna yang bekerja pada frekuensi 3.5 GHz menggunakan bahan FR-4 epoxy. Berdasarkan hasil simulasi dan pengukuran, antena sub-array 2x2 desain 2 (desain yang menggunakan tambahan 9 buah parasitic patch) memiliki kinerja parameter antena yang lebih baik dibandingkan antena sub-array 2x2 desain 1 (desain yang menggunakan tambahan 5 buah parasitic patch) meliputi parameter return loss, VSWR, bandwidth dan mutual coupling. Hal tersebut diakibatkan penambahan jumlah parasitic patch yang mampu meningkatkan kualitas parameter antena yang diinginkan. Hasil pengukuran antena sub-array 2x2 desain 2 menunjukkan return loss sebesar -28.39 dB, VSWR sebesar 1.081, bandwidth sebesar 720 MHz atau fractional bandwidth sebesar 19.82 %, dan mutual coupling sebesar -29.56.

The fifth generation (5G) wireless standard significantly increases wireless system performance in terms of data speed, system capacity and device connectivity. Massive MIMO technology makes it possible to use an array antenna with several hundred antennas simultaneously at the same time and frequency so that the spectral efficiency or the amount of information transmitted will increase. It is considered as one of the most promising technologies for the development of broadband networks in the future that will save energy, safe, and strong.
In this research, the microstrip antenna design and sub-array microstrip antenna design will be carried out. The antenna design process begins by determining the antenna enhancement parameters. Next, design a single microstrip antenna, start the process of widening the bandwidth using the parasitic patch technique, then design the microstrip antenna sub-array.
Simulation results are verified by measurement results. The antenna made is an antenna that works at frequency of 3.5 GHz using FR-4 epoxy material. Based on simulation and measurement results, 2nd design (designs that use an additional 9 parasitic patches) of 2x2 sub-array antennas have better antenna parameter performance than 1st design (designs that use an additional 5 parasitic patches) of 2x2 sub-array antennas include parameter such as return loss, VSWR, bandwidth and mutual coupling. This is due to the addition of the number of parasitic patches that can improve the quality of the desired antenna parameters. The measurement results of the 2nd design 2x2 sub-array antenna show return loss of -28.39 dB, VSWR of 1.081, bandwidth of 720 MHz or fractional bandwidth of 19.82%, and mutual coupling of -29.56.
