•Applied FIT and FEM.•Compact microstrip antenna.•5G applications.•CST and HFSS. This study provides a deeper knowledge of the usage of finite integration techniques (FIT) and the finite element method (FEM) for analyzing various microstrip antenna shapes such as rectangular, circular and triangular patches. These patch shapes are fabricated practically and the efficiency of both mentioned methods have been identified through the evaluation of the microstrip antenna parameters such as, gain, bandwidth, VSWR, return loss S11, directivity and ration pattern operating at 28 GHz. Comparison between measured and simulated results with both techniques reveals that the FIT better for all types of microstrip antennas patch shapes whereas FEM is only reliable for rectangular microstrip antennas shape due to its regularity in its configuration. In addition, a good agreement between the results of the proposed antenna parameters with previously research works operating at the same frequency are also identified. Beside of this, our proposed antenna has the advantage of small size of the order of (5.2 mm3) which is compact and suitable for the 5 G wireless communication system applications. Furthermore, with this small profile configuration, the antennas still provide high radiation performance with a bandwidth of the order of (900 MHz), gain of (6 dB) and directivity of the order of (7 dB).
