Abstract: In this paper, we analyse the performance of Hexagonal patch antenna array using microstrip and coaxial feed techniques. Here antenna array is mainly designed for X-Band applications. Antenna is simulated using HFSS 14.0 and performance measures of hexagonal patch antenna array such as return loss, gain, radiation pattern and VSWR are measured and compared for both microstrip and coaxial feeding techniques.
