    A low profile, flexible, circularly polarized antenna based on the artificial material methodology is introduced in this paper. The antenna footprint is 20 mm � 15 mm, where it is excited by the Co-Planar Waveguide (CPW) configuration. Flexibility is achieved by incorporating Rogers Ultralam 3850 as the antenna substrate. By protruding an inverted T-shaped slot from the radiator to the extended CPW ground plane, circular polarization was achieved. The design radiates at 5.2 GHz with a-10 dB bandwidth of 29.7 MHz, gain of 0.7 dBic, boresight Axial Ratio (AR) of 0.86 dB, and 3 dB-AR bandwidth of 64.3 MHz. With such characteristics, the antenna is targeting wearable and Wireless Local Area Network (WLAN) applications. 2019 IEEE.
