Design of Microstrip Antenna Array and Analysis of different Beamforming techniques for mm-wave MIMO Systems

This project work is focusing on the design and simulation of array antenna that operates in the mm wave frequency band and also analyze and implement the beamforming technique suitable for the proposed antenna design. The optimum weights calculated from the LMS Algorithm are used to excite the antenna array in ANSYS HFSS to observe the beamforming and the radiation pattern in the direction of desired signal. The obtained results were analyzed and compared with the theoretical values. The result consists of the measure of various parameters that are required to analyse the performance of an antenna like return loss, gain, directivity and bandwidth. . The antennas are implemented in ANSYS HFSS and antenna characteristics are compared based on the Return loss, VSWR, 3D polar plot and radiation pattern which are tabulated. These parameters were also observed for an 8, 16, 32, 64-element antenna array and a significant increase in gain and directivity was observed. All simulations are performed on MATLAB.
