Abstract: This paper presents two antennas, one is linearly polarized dual frequency hexagonal microstrip patch antenna and other is wide band circularly polarized hexagonal microstrip patch antenna. The presented antennas are designed for Ku band applications. Dual frequency is obtained by introducing a rectangular shaped slot on the hexagonal patch. Both antennas are simulated using HFSS 14.0 and performance measures of an antenna such as return loss, voltage standing wave ratio (VSWR),axial ratio, peak gain and radiation pattern are measured.
Keywords: Hexagonal, slot, axial ratio, circular polarization, linear polarization.
