The design and simulation results of linearly polarized and circularly polarized microstrip patch phased antenna
arrays operating at 5 GHz is presented. The phased arrays are employed by providing the progressive phase excitations at the
source ports. The work presents the design structures of 1x4, 2x4 and 2x8 linearly polarized phased arrays and 1x4, 2x4 and 2x8
circularly polarized phased arrays upon a FR4 substrate of thickness 1.6 mm. The linear polarized phased array antennas were
designed for comparison
