This manuscript presents various technical issues concerning the development of rectangular patches array antennas deployed in a-3D weather radar system. It was initially designed to operate at 9.35 GHz. The fabricated 20-elements patch array was remodeled and further investigated to fully characterize its fundamental electrical properties. To guarantee more accurate and valid numerical modeling two rectangular patches arrays, i.e. two and twenty elements arrays, were built and computed. The recorded results of two kinds of array antennas have been verified and confirmed very close agreement in terms of 3D and 2D-beampatterns, S11, axial ratio (AR) and gain properties. The 90 degrees passive phase shifter was used to create the CP behavior on the whole patches antenna array. |
