Abstract
Wireless Gigabit or WiGig is a wireless network technology with IEEE 802.11ad standard in the 60 GHz frequency spectrum, namely high-speed WiFi up to 7 Gbps which is 7 times the speed of the current WiFi network. In general, high frequencies have a transmit power that is close and susceptible to attenuation, so we need a type of antenna that is high gain. One type of antenna that can be chosen is the reflectarray antenna. The reflectarray antenna is an antenna that combines the features of the reflector and array configuration in one antenna so that it has the characteristics of point to point transmission and the beam is more focused in one direction. In this final project, a reflectarray antenna is designed and analyzed at a frequency of 60 GHz and realized using a RO4003C type PCB with (εr = 3.55; h = 0.51 mm). The antenna design will be simulated using the Ansof High Frequency Structure Simulator (HFSS) v15.0 software, as well as the realized antenna can work at a frequency of 60 GHz and is high gain ≥10 dBi. Keywords : WiGig, WiFi, Reflectarray, High Gain Wireless Gigabit atau WiGig adalah teknologi jaringan nirkabel dengan standar IEEE 802.11ad pada spektrum frekuensi 60 GHz, yaitu WiFi berkecepatan tinggi hingga 7 Gbps yang merupakan 7 kali kecepatan jaringan WiFi saat ini. Pada umumnya, frekuensi tinggi memiliki daya pancar yang dekat serta rentan terhadap redaman sehingga dibutuhkan jenis antena yang bersifat high gain. Salah satu jenis antena yang dapat dipilih adalah antena reflectarray. Antena reflectarray merupakan antena yang menggabungkan fitur reflektor dan konfigurasi array dalam satu antena sehingga memiliki karakteristik pemancaran sinyal point to point dan pancaran lebih terfokus pada satu arah. Pada tugas akhir ini, dilakukan perancangan dan analisa antena reflectarray pada frekuensi 60 GHz dan direalisasikan menggunakan PCB jenis RO4003C dengan (εr = 3.55; h = 0,51 mm). Perancangan antena akan disimulasikan menggunakan Software Ansof High Frequency Structure Simulator (HFSS) v15.0, serta antena hasil realisasi dapat bekerja pada frekuensi 60 GHz dan bersifat high gain ≥10 dBi. Kata Kunci : WiGig, WiFi, Reflectarray, High Gain
