In this paper a rectangular dielectric resonator antenna (DRA) fed by a microstrip line is studied. Therefore, at first radiation performance of DRA is studied, and the improvement techniques are reviewed. Then propose a novel configuration for broadening of the impedance bandwidth. In the proposed arrangement, by using multi-segment structure with different dimensions, increase the antenna impedance bandwidth. However for decreasing the design parameters, variations limited to the segments width. So, with the non-uniform configuration by variable width, it is possible to create remarkable increase in frequency bandwidth. Utilizing the symmetrical seven-segment DRA and skillfully varying its aspect ratio, an appropriate structure is obtained that illustrates more than 52% impedance bandwidth for S11>10.
