Multi-bandwidth CPW-fed open end square loop monopole antenna for energy harvesting

Compact CPW-fed open end square loop monopole antenna is presented in this paper. The antenna can harvest at different radio frequencies. Multi band antenna operation has been created at 1.8, 1.9, 2.4 and 5.2 GHz. The multi-bandwidth coplanar waveguide antenna (MCPW) is designed and fabricated on a very thin and low-profile substrate.
