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 5.5GHz. 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.
