Miniaturized broadband circularly polarized antenna allocated in a rotational symmetry

This paper proposes a broadband circularly polarized antenna that is composed of inverted F and L antennas on the ground plane, and is allocated in a rotational symmetry. The height and diameter of our proposed antenna is respectively 0.10λ 0 and 0.33λ 0 . The relative bandwidth satisfied with VSWR<3 in each band is 10.7% and 6.9%.
