A novel wide band antenna for WLAN applications

Abstract

With the emergence of WiMax and UWB for high-speed wireless applications and the existence of IEEE 802.11 a/b/g/n WLAN, antenna vendors are faced with the challenge of creating compact, wideband multiple-input multiple-output (MIMO) antennas for wireless applications. The wideband MIMO antenna presented in this paper is a novel antenna design based on pure dielectric antenna (PDA) technology. Pure dielectric antennas are like dielectric resonator antennas in that both typically use high εr dielectric material, however we have found that the PDA does not follow the general design relations of a DRA (R.K Mongia and P. Bhartia (1994)).
