چکیده
The Design of hexagonal patch is presented withsingle coaxial feed namelysimple hexagonalpatch,hexagonal patch with one triangular slot in ground for circular polarization. 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

متن کاملA Capacitive Fed Microstrip Patch Antenna with Air Gap for Wideband Applications (RESEARCH NOTE)
In this paper a microstrip antenna on a suspended substrate with capacitive feed is presented. capacitive feed is created by a slot within the rectangular patch around the feed point. The proposed antenna exhibits a much higher impedance bandwidth of about 47% (S11 < −10 dB). Effects of key design parameters such as the air gap between the substrate and the ground plane, the gap width between r...

In this paper, we propose a new compact quasi-fractal shaped microstrip antenna that consists of a hexagonal patch as the main radiator and a complementary stacked patch as the parasitic element. The overall surface of the proposed quasi-fractal patch is about 55% lower than the conventional hexagonal patch.
