A ring dielectric resonator antenna (DRA) design with an air gap between the dielectric resonator and ground is presented for broadband applications. In this proposed antenna, micro strip line feeding is used for easy fabrication. This DRA is simulated using a CST microwave studio suite TM 2010. The simulated results show the wider impedance bandwidth of around 86% covering the frequency range of...
A novel P-shape wideband dielectric resonator antenna design is presented for wireless application in this paper. It is described by using a P-shape dielectric resonator with high dielectric constant (εr = 30) that is placed on the truncated ground plane, a wideband impedance bandwidth of about 64% (for VSWR≤2), covering the frequency range of 3.40-6.58GHz is achieved. Analysis...
In this paper a novel design procedure to obtain wideband and small size dielectric antennas using high dielectric constant material is described. It is shown that by selecting the resonator shape and creating a notch on the dielectric resonator, it is possible to design rectangular dielectric resonator antenna which compact size and wide frequency coverage. Simple formulas are presented to illustrate...
A novel wideband dielectric resonator antenna is proposed, where an inverted L-shaped dielectric resonator is excited by a vertical trapezoid-patch. The antenna has a simple structure and provides an impedance bandwidth of 73.0% for VSWRles2, covering the frequency range from 3.80 GHz to 8.17 GHz, and with a stable broadside radiation pattern.
