Abstract
Antennas play a significant role in wireless communication systems and have a direct impact on their performance. In particular, Millimeter-wave systems have gained popularity in the wireless communication sector in response to rising demand for greater throughputs, reduced interference, and smaller mobile terminals. Furthermore, recent developments in wireless technologies and procedures have allowed for such systems to be brought to market. However, atmospheric losses are a significant barrier when working with millimeter waves. High-gain array antennas are a solution to this which due to its compact size and low profile, (as is the case with millimeter-wave planar array antennas), have found widespread applications in modern wireless communication.Millimeter-wave phased array antennas provide the potential to optimise interference while making the most of available bandwidth. This is because they can dynamically aim their primary beam (the strongest possible radiation) in the direction of the target.
The front end of a 75 GHz phased array antenna that supports electronic beam steering in two dimensions is the subject of this report’s design and study. To investigate the efficiency of such an antenna, a 16-element rectangular planar array of rectangular microstrip antenna elements would be modelled and optimized as a starting point. The array’s radiation characteristics would next be examined, and beam steering in various directions would be simulated. Using the same methods, a massive phased array antenna (80x80, 160x160, and 320x320) for use as a W-band transmitting earth station terminal antenna for satellite communication would be designed and simulated to investigate its performance and viability.
