Abstract :
Open-sleeve dipoles are widely used antennas because they have several parameters that can be adjust to achieve wide range of operating bandwidth. In this paper, an end-loaded planar open-sleeve dipole (ELPOSD) with a magnetic dielectric material based planar EBG substrate is investigated. With S11 < -10 dB, the ELPOSD has a bandwidth of 5.15-10 GHz and the broadband gains precede 6.4 dBi. Including the thickness of the EBG substrate, the antenna height is reduced 60% at the central frequency, compare to the traditional quarter wavelength cavity backed ELPOSD antenna. Especially, the lower frequency reaches 5.15 GHz, which is reduced 1.1 GHz.
