Design of dual band dielectric resonator antenna with slot for WLAN applications

To realize dual frequency service for WLAN applications, a mixed breed double band dielectric resonator antenna with parasitic opening encouraged by microstrip feed line is proposed. The recommended radio wire configuration contained circular dielectric resonator and U - space resonator. The U - space is composed on the ground plane of dielectric resonator antenna (DRA). By regulating design parameters, the circular dielectric resonator engage at upper band (5.6 GHz) and U - space slot engage at secondary band (2.4 GHz), the pair of resonators are diverging with two distinct radiation designs. In order to resolve the exploit of the recommended design, the practical parameters being return loss transmission capacity, voltage standing wave ratio and radiation designs are seen by the simulation of configuration with high frequency structure simulator (HFSS). The recommended antenna model is reasonable for WLAN applications.
