Abstract :
The dipole antenna is a simple and fundamental radiator and meets requirements for an antenna structure with a low profile and compact configuration. However, it cannot radiate efficiently near a perfect electric conductor (PEC) ground plane due to the reverse image currents. The paper presents the idea of using an EBG ground plane to improve the radiation efficiency of a nearby planar dipole antenna. The validity of the idea has been demonstrated by both FDTD simulations and measured results. The proposed antenna structure has a good potential for wireless communications, such as WLAN, and radar systems.
