A compact, wideband, circularly polarized (CP) dipole antenna is presented. The antenna consists of a directly driven, crossed Egyptian axe dipole (EAD) antenna stacked seamlessly in parallel with an inductive parasitic grid array metasurface within a circular package. The grid array structure is introduced to collaborate with the EAD antenna in producing overlapping resonances to achieve wideband CP radiation. The simulated impedance bandwidth, where |S11|< -10 dB, is from 1.58 to 2.06 GHz (26.3%). The 3-dB AR bandwidth is from 1.67 to 2.08 GHz (21.8%). The consequent overlapping bandwidth is from 1.67 to 2.06 GHz (20.9%). The total dimensions of this very compact, low profile antenna are pi times {left({0.19{{{lambda }}_0}}right)-2} times 0.0014{{{lambda }}_0} = 1.59 times {10-{ - 4}}{{{lambda }}_0}-3, where λ0 is the wavelength of the lower bound frequency, 1.67 GHz. Moreover, the antenna radiates bidirectional electromagnetic fields with high radiation efficiency across the entire overlapping bandwidth.
