Abstract :
A novel tri-band circularly-polarised antenna for coherent electromagnetic radio tomography (CERTO) application is proposed. Based on the traditional crossed-dipole and the theory of transmission line, the antenna was designed for tri-band frequencies operation. Good radiation patterns and axial ratio are presented.
