Enhancement of printed dipole antennas characteristics using semi-EBG ground plane

Electromagnetic band gap (EBG) structures have been used in many antenna designs to improve their performance. This paper investigates the performance of a dipole antenna near the edge of a ground plane, a popular setup in various wireless communication Systems. To increase the radiation efficiency, a printed dipole antenna with semi-EBG ground plane is proposed. Both FDTD simulations and experimental results demonstrate the validity of this antenna design.
