Abstract :
This paper describes a novel ultra-wideband quasi-Yagi circular dipole antenna. The antenna consists of two parallel circular dipole radiators of different resonant lengths. The bandwidth which can meet both impedance and radiation characteristic requirements is greater than 100%. The important advantages of this antenna are ultra-wideband, directive property, and low cross polarization levels with high front to back lobe ratio. A prototype is fabricated and measured.
