Abstract :
A Dielectric resonator antenna design is presented for Wireless Local Area Network (WLAN) applications. By using a dielectric resonator with an inverted U-shape cross section and optimized rectangular patch adhered in between the dielectric resonator as a feeding mechanism, an impedance bandwidth of about 15.7% and covering a frequency range of 5.1 to 5.97 GHz is achieved and resonating at 5.5 GHz. The proposed antenna is suitable for wireless local area networks (WLAN) applications in 5-6 GHz frequency range. This U Shaped DRA exceeds the bandwidth requirements for the IEEE 802.11a wireless local area network (WLAN) applications (5.15-5.35 GHz and 5.725-5.825 GHz) within a 2:1 VSWR. Parametric studies of the antennas with CST microwave based design data and simulated results are presented here.
