A Flower-Fractal Based Circularly Polarized Wide Beam-Width Folded Antenna

A Flower-Fractal based circularly polarized folded microstrip patch antenna is proposed in this paper. It is a wide-beamwidth folded patch antenna that can emit circularly polarized radiation. Due to folded at the edges as well as Flower-fractal based slotted design, the antenna is miniaturized up to 49%. Having miniaturization, the antenna is placed in the dense aerodynamic wireless devices using surrounding dielectric substrate and the metallic block, as a result the half power beamwidth (HPBW) is increased by 110
^◦
and the axial ratio beamwidth (ARBW) is raised by 120
^◦
. So the antenna becomes capable to capture signals from the broad elevation angle.
