【 摘 要 】

LTE is a standard of wireless communication access by using GSM/EDGE and UMTS/HSPA technology for high-speed data transfer rates. This technology can download and upload with the speed up to 300 Mbps and 75 Mbps respectively. LTE technology using MIMO system can increase the data rate and capacity on sending and receiving simultaneously on a radio frequency channel so that the antenna which is used for LTE band-3 works at 1.8 GHz also using MIMO structure. In this paper, the authors will propose a MIMO 2x2 antenna with directional radiation patterns that works at LTE band-3 using two types of patches, which are the parasitic and main patch. In this simulation, we use FR-4 as the substrate. This substrate has a dielectric constant of 4.5, and the thickness is 1.6 mm. The method that is used in this research is design and simulation. The calculation, design and simulation process on this research the authors use the CST Studio Suite Software. The target results from this research are the antennas works at 1.8 GHz LTE band; the gain is more than 6 dBi; diversity polarization is vertical and horizontal, coupling between two antennas is less than -20 dB, and the antenna bandwidth is 200 MHz from 1.7 to 1.9 GHz for VSWR less than 2 with directional radiation patterns.
