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.EnglishOctober University for Modern Sciences and Artsجامعة أكتوبر للعلوم الحديثة والآدابUniversity of Modern Sciences and ArtsMSA UniversityCircularly polarized antennaCRLHMetamaterialWearable antennaWLAN applicationConference Paperhttps://doi.org/10.1109/APUSNCURSINRSM.2019.8889131
