A Small Printed Quasi-Self-Complementary Antenna for Ultrawideband Systems

A novel and simple ultrawideband (UWB) printed quasi-self-complementary antenna is presented. The proposed antenna, which is fed by a microstrip line, has been demonstrated to provide an ultrawide 10-dB impedance bandwidth with satisfactory radiation properties. It also features both physically and electrically small dimensions, 16 mm times 25 mm in a physical size and 0.24lambda in an electrical size, respectively. The key parameters that affect the performance of the antenna are investigated. A good agreement is achieved between the simulation and the measurement.
