Abstract :
An ultra-wideband dielectric resonator antenna (DRA) is studied and investigated for wireless application. The dielectric resonator is fed by a microstrip line. The overall size of the proposed DR antenna is 20 × 35 mm2, and the thickness of the dielectric resonator is only 5.12 mm, which is suitable for mobile device. The design simulation is done by using computer simulation Technology Microwave studio suite 2012 (CST). The results represent that by using N-shaped dielectric resonator, a wideband impedance bandwidth of 111% for VSWR≤ 2 covering a frequency range from 3.59 to 12.61 GHz. A parametric study is presented.
