Abstract
Dengan berkembangnya ilmu pengetahuan tentang telekomunikasi, 5G telah membuat banyak peneliti tertarik. Pita 26 GHz merupakan salah satu pita yang digunakan sebagai frekuensi gelombang milimeter untuk sinyal 5G. Gelombang milimeter mempunyai bandwidth yang lebar sehingga dapat mentransimikan data lebih cepat
Ukuran antena microstrip yang kecil, membuat microstrip menjadi murah dan cocok untuk dijadikan antena array. Meskipun antena array dapat membuat gain antena tinggi, namun ada kendala pada antena array yaitu mutual coupling. Mutual coupling dapat mengganggu kinerja antena array karena daya yang seharusnya dipancarkan justru diserap oleh antena didekatnya.
Salah satu cara untuk mengurangi mutual coupling adalah dengan mengimplementasikan defected ground structure. DGS (Defected Ground Structure) sangat popular karena hanya mempunyai ukuran yang kecil dan tertanam di ground plane pada antena microstrip. Pada topik ini saya akan menggunakan salah satu jenisnya yitu S-Shaped Defected Ground Structure, karena dapat mengurangi arus induksi pada permukaan secara signifikan karena terbatasi.

With the development of science about telecommunications, 5G has attracted many researchers. The 26 GHz band is one of the bands used as a millimeter wave frequency for 5G signals. Millimeter waves have a wide bandwidth so they can transmit data faster
The small size of the microstrip antenna makes the microstrip inexpensive and suitable for use as an antenna array. Although the antenna array can make the antenna gain high, there is a problem with the antenna array, namely mutual coupling. Mutual coupling can interfere with the performance of the antenna array because the power that should be transmitted is absorbed by nearby antennas.
One way to reduce mutual coupling is to implement defected ground structure. DGS (Defected Ground Structure) is very popular because it only has a small size and is embedded in the ground plane of the microstrip antenna. In this topic, I will use one of the types, namely S-Shaped Defected Ground Structure, because it can reduce the induced current on the surface significantly because it is limited.
