A novel wide band antenna for WLAN applications

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 /spl epsiv//sub r/ 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)).
