Abstract

A compact rectangular Dielectric Resonator Antenna is designed for wireless applications that provides good response in frequency range from 2.3 GHz to 3.1 GHz. One of the most striking feature of this design is modifying the feeding structure. The proposed rectangular dielectric resonator is of size 50 × 50 × 1.6 mm3 is fed using trapezoidal microstrip feed line formed by joining 17.3 mm triangular patch with a microstrip line. FR4 material is used for substrate with relative permittivity of 4.6. Dielectric material used is ceramic has a high relative permittivity of 30. Rectangular dielectric has dimensions of 20 × 18 × 15 mm3. The simulated results show that the antenna provides a wide impedance bandwidth of 28.10% (2.3 - 3.1 GHz) and can be used for wireless applications.
