Abstract
A compact and circularly polarized CPW-fed antenna for ISM, Biomedical and satellite applications is presented. The L-shaped stub in the ground is used to improve the impedance matching and perturb the current which is responsible for circular polarization(CP). The |S11| in dB of the antenna varies from 5.35 GHz to 8.88 GHz. The 3dB Axial Ratio of antenna varies from 7.83 GHz to 8.77 GHz. The antenna is analyzed for wearable applications on a three-layer skin phantom model and the SAR value obtained is 0.38 W/Kg, which is below the maximum permissible level.
