Electronic steering without mechanical motion across multiple beams makes the phased array antennas popular in current communication systems, radar, and even 5G. The current paper narrates the design and optimisation of a phased array antenna simulated in Ansys High-Frequency Structure Simulator (HFSS). The suggested antenna is made of a 4×4 patch array of microstrip working in the 10 GHz. The design cycle involves identification of elements, arranging them in an array format and optimization of parameters e.g. impedance matching, radiation pattern and beam steering ability. Return loss, gain and sidelobe levels are analyzed by means of HFSS simulations. The outcomes show an antenna that is well matched with gain 15.2 dBi and maximum beam steering capacity of +/-300. The paper shows the usefulness of the HFSS in the designing and optimization of phased array antennae to meet high performance applications.
