In this paper, a rectangular dielectric resonator antenna (DRA) suitable for wideband applications is presented and a band notch of WLAN (5.15-5.75) GHz is proposed. The DRA is mainly composed of a 20 x 20 mm rectangular dielectric resonator, coated with metal on the top surface, and a circular monopole excitation patch with an air gap in-sert. A coaxial line feed is used to excite the circular, planar monopole. An open-ended quarter wavelength C-shaped slot is embedded in the circular patch to create the notched band. The simulated results demonstrate that the proposed design produces an impedance bandwidth of more than 80%, rang-ing from 3.10 to 7.25 GHz for a reection coefficient of less than -10 dB and with a band rejection at 5.50 GHz. Band notch characteristics, VSWR, and radiation patterns are stud-ied using the HFSS high-frequency simulator and CST Studio software. [ABSTRACT FROM AUTHOR] |
