Abstract
Conventional Yagi antenna provides a unidirectional radiation pattern but is not preferred for wideband applications. The proposed quasi-Yagi antenna consists of a driver dipole, two directors and the ground plane as the reflector. Four extended stubs are added to the ground plane to improve the bandwidth. A U-shaped defect is also introduced in the ground plane which enhances the bandwidth further. Simulation results show that the proposed antenna provides a 111.31 % bandwidth that ranges from 3.94 to 13.83 GHz. The maximum gain offered by the antenna is 5.92 dBi.
