The circular polarization of two antennas are obtained with 1.31% axial ratio(AR) for simple hexagonal patch, 4.43% axial ratio hexagonal patch with slotted ground hexagonal patch antenna. The impedance band widths of these antennas are achieved as 1.85% for simple patch, 5.21% for slot ground patch. The feedlocation is optimized for the best impedance match to a 50Ω coaxial feed line. The average gain and radiation efficiency of antenna are also evaluated. Simulatedresults are verified experimentally Index Terms-Microstrip antenna,hexagonalmicrostrip antenna, circularly polarized microstrip antenna, single coaxial feed.Read More
