M Microstrip antenna has a number of advantages including the shape is small, light and able to customize the installation place. In addition to excellence microstrip antenna also has shortcomings, namely the narrow bandwidth and reinforcement (gain) is low,. One of the solutions of these problems is to add U-shape on the element of microstrip antenna.In this study, namely designing and implementing Double U-shape microstrip antenna array. Working at a frequency of 1800 MHz (1.8 GHz) so that the application can support a Long Tenn Evolution (LTE). While the type of substrate used is Epoxy FR4 with relative permittivity value = 4.4.From the simulation has been performed using AWR Design Environment is obtained in accordance with the specifications of antenna, at a frequency of 1.8 GHz with a VSWR limit < 2.0 earned 176.5 MHz bandwidth, and gain 8,738 dBi antenna. After doing the design of the AWR Design Enviromnent, made the implementation of the antenna based on simulation results. The results of the measurement of antenna impedance, VSWR, include radiation pattern, and the gain. The microstrip antenna has some differences with the measurement results, namely on VSWR measurement results obtained 1.34, 148 MHz of bandwidth, and 7.125 dB of antenna gain. But such differences meet the specifications with the antenna simulation results. The difference between the simulated results with measurements due to the State of the environment at the time of the measurements is not ideal.
