This article reveals the characteristics of a probe-fed wideband circularly polarized (CP) annular ring textile antenna (ARTA). The proposed ARTA is fully flexible due to a conductive stack fabrics configuration for GSM-1800/ISM-2.4 GHz. The foremost aim of this article is to realize its performance under bending circumstances for wearable applications. The combinations of woven and non-woven polyester fabrics are used as a high-low substrate material to attain superb impedance bandwidth (BW) and worthy surface wave efficiency. A decent CP performance is realized by choosing the precise dimension of notches. It has measured and simulated impedance and the axial ratio (AR) BW of 18.33%, 13.88%, 7.86%, 2.86% and 3.97% in the lower and upper band, respectively. The optimization of CP in the upper band is under process. Results clarify that the CPARTA is beneficial for wearable and wireless application under bending circumstances. The proposed method is appropriate where a wide-range of CP bandwidth is essential.
