    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.

    This paper presents a high gain of 2 × 1 circularly polarized rectangular microstrip array antenna for wide communication. This paper study the design and the simulation of the array antenna in terms of S-parameter, antenna gain, and the axial ratio. The 2 × 1 array antenna with dimension of 130 × 80 mm is proposed. The presented design is composed of two elements of microstrip patch antenna with an array configuration. The truncated edge of the patch and the inclined slot are the techniques used in order to achieve circular polarized capability. The antenna is fed by microstrip transmission line with full ground plane and etched on Rogers RT 5880 substrate with 2.2 and 0.51 mm of dielectric constant and thickness respectively. The antenna substrate is layered by 3 layers in order to increase the substrate thickness to 1.53 mm. The patch antenna is fed by using microstrip transmission line which separated into two lines based on the number of radiating elements. The quarter wave impedance matching technique is used to match the radiating patch. The 50 Ω transmission line are utilized to be matching between 70 Ω and 100 Ω. The 2 × 1 array antenna achieved a gain of 10.77 dB with a return loss of −24. 63 dB at a desired frequency of 5.8 GHz.
