In this letter, a wideband right-hand circularly polarized high-gain 4 × 4 microstrip patch array antenna on a polyethylene terephthalate (PET) film flexible substrate material is investigated. A comparison between the planar and curved surface study is also presented to show impact of curving the array on antenna performance parameters since it is employing a flexible substrate material. Due to some unknown properties of the PET material, some disagreement is noticed between the simulated and measured results in reflection coefficient magnitude, axial ratio, and gain in addition to radiation patterns. The radiation patterns are consistent with some rise in cross-polarization levels.
