Pengaruh Posisi dan Ukuran Slot Terhadap Unjuk Kerja Antena Mikrostrip Rectangular Patch Dual Band 1800 MHz dan 2100 MHz
AbstractNowadays many communication systems use the LTE network. This refers to an ongoing process to improve wireless technology. The latest technology like LTE certainly has to use a new device, in addition to different speeds, the frequency used must also be adjusted. Data from 4G LTE technology is received by users through 4G antennas. 4G antennas are generally small and thin. One antenna that has this character is a microstrip antenna. In this study, a rectangular slot microstrip antenna will be designed by iterating the position and dimensions of the slot along with iterations of the dimensions and position of the slot to determine the most optimal position and slot size for dual band 1.8 GHz and 2.1 GHz antennas. For the type of substrate used is FR-4 Epoxy with h = 1.6 mm and Îµ_r = 4.6. This antenna uses a rectangular patch and rationing technique used by microstrip line. From the results of the study, it was found that by means of aniterating the position of the slot size it would provide the best results compared to the size of the slot to position the slot. So that the most optimal results for dual band 1800 MHz and 2100 MHz antennas with return loss of -31,986 dB and -54,647 dB VSWR 1,027 and 1.00 impedance of 50,86 86 gain 6,720 dB and 4,575 dB. Keywords: microstrip antenna, dual band, rectangular slot, VSWR, gain, impedance, optimal LTE
