This project gives a detailed study of the Design and Performance analysis of series fed patch antenna array for 60 GHz system applications. The patch array designed in this project will act as an active element and can be used as the feed antenna of the dielectric flat lens antenna which is highly directive at 60 GHz. CPW (Coplanar Waveguide) is used as the feeding technique of the antenna array because it has lower transmission loss, lower profile especially on high frequency band. The purpose of the array is to perform the beam scanning with the shift in the frequency over the complete range of V-Band i.e. 57 GHz to 64 GHz. The designs are simulated in HFSS which is a high frequency simulator for designing such antennas. Due to the low profile and small weight of these antennas, they are constructed in microstrip technology which allows easy integration with printed circuits. For the fabrication of antennas Laser machine LPKF and photolithographic process are used.
