    This research presented a perpendicular high isolation MIMO antenna for LTE advance application. A high gain perpendicular MIMO antenna is concentrated on designing used in LTE advance application. The issues of low isolation of conventional antenna can be solved by structuring a MIMO antenna in order to increase the isolation in LTE advance application. Generally, the array antenna design causes a bigger antenna size and has a mutual coupling which lead to spectral efficiency damage and reduce the MIMO antenna framework performance. The substrate material like FR-4 is choosing as a dielectric substrate due to its good performances for many applications beside it has a low cost and more usable. The advantage of copper such as has a great relative material, cheaper and easy to construct is choose in this project as a conductive material. ADS software has been utilized for the structure stage to design the antenna. Then, the results are evaluated in terms of return loss (S11 and S22), mutual coupling (S12 and S21), match impedance, directivity, radiation pattern, gain and radiated power. Vector Network Analyzer (VNA) is used to measure the fabricated antenna. The factor of cable loses and the soldering technique will make the measurement result was slightly change from the simulating result. However, the antenna design satisfied the proficiency necessity of the antenna which the frequency is drop at 2.5 GHz with the return loss is below than −10 dB.

    In this paper, the MIMO antenna design for LTE Advance Application is realized. The paper focused on designing high gain MIMO antenna for LTE Advance Application. The purpose of designing a MIMO antenna is to fix the problem of low/moderate gain of SISO antenna since to have higher gain in LTE Advance normally is by having array antenna which lead to larger antenna and higher cost and mutual coupling between MIMO before can cause loss of spectral efficiency and degrade performance of a MIMO system. The designed antenna used FR-4 board as the substrate material due to its good parameters for most application. It is also more available and much cheaper than any other PCB material. Meanwhile, copper has been chosen as conductive material which copper is high relative and also cheap. For the designing stage, Advance Design System (ADS) software has been used to design the antenna. The ADS software also has been used for the simulation of the designed antenna in terms of return loss (S11) and (S22), mutual coupling (S12) and (S21), gain, directivity, radiation pattern, power radiated and also impedance matching. For the measurement stage, the fabricated antenna has been using by Vector Network Analyzer (VNA). From this project, it can be seen that the measurement results were slightly different from the simulation results due to a few factors such as cable losses, and also soldering technique. However, the designed antenna still met the requirement of efficiency which is less than -10 dB of return loss and get at a frequency of 2.5 GHz.
