This paper reveals the characteristics of probe-fed wideband circularly polarized (CP) annular ring textile antenna (ARTA). The proposed ARTA is fully flexible due to conductive stack fabrics configuration for GSM-1800/ISM-2.4 GHz. The foremost aim of this paper is to realize its performance under bending circumstances for body wearable application. 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 axial ratio (AR) BW of 18.33%, 13.88%, 7.86%, 2.86% and 3.97% in lower and upper band respectively. The optimization of CP in upper band is under process. Results clarifies that the CPARTA is beneficial for body wearable and wireless application under bending circumstances. The proposed method is appropriate where wide-ranging of CP bandwidth is essential.
