A microstrip patch antenna is one type of antenna that is currently widely used in wireless communication systems. This antenna is an option because it has several advantages, such as its lightweight, small size and easy to fabricate. However, one of the disadvantages of this antenna is the narrow bandwidth. In this study, bandwidth will be increased in a single circle microstrip patch antenna. This increase in bandwidth aims to make the antenna designed to work for LTE band 3 applications with a frequency range of 1710-1880 MHz. Increasing bandwidth can be done using the Split Ring Resonator (SRR) Metamaterial. Antenna simulation and optimization were carried out using 3D electromagnetic simulator using FR-4 substrate with a thickness of 1.6 mm and a dielectric constant of 4.3. Based on the simulation results, obtained antenna bandwidth of 310 MHz with a frequency range of 1620 - 1930 MHz for return loss of less than -10 dB. The antenna gain is around 2.1-2.5 dBi with directional radiation patterns. It can be concluded that this antenna can be used for LTE band 3 applications. © 2019 IOP Publishing Ltd.
