Graphical abstract Start Menentukan substrat antena Menghitung dimensi antena pada frekuensi 2450 MHz Menghitung saluran catu 50 ohm Merancang antena dengan bantuan perangkat lunak Simulasi dengan perangkat lunak RL ≤-10dB VSWR ≤ 2 Stop ya tidak Abstract In this research, the design of microstrip antenna with patch circular shape using FR-4 Epoxy substrate with ɛr=4.3 h=1.6mm and loss tangen=0,0265. To increase the gain value, will be used the 2x1 array method. Furthermore, to widen the Bandwidth, will be used the power supply with proximity technique. The purpose of the use of array and proximity method is to increase the value of Gain and Bandwidth. From the simulation results the value of Return Loss is-19, 85 dB, VSWR is 1.227 and Gain is 7.091 dB at 2450 MHz frequency. With that data, array method can increase Gain by 38% and with use of Proximity method can increase Bandwidth by 162%.
