Abstract :
In this paper, a compact rectangular dielectric resonator antenna is proposed by using fractal geometries. The Minkowski fractal patch is used on DRA´s top to reduce the resonant frequency of the antenna. Numerical results are computed and compared up to three iterations. The fractal iterations offer an additional 19% reduction in the resonant frequency compared to a full size metal top. Switches are proposed at suitable places to achieve frequency reconfigurability. A 43% reduction in the resonant frequency (3.312GHz) is shown when switches are in OFF state compared to a conventional RDRA (5.84GHz) without any increase in antenna size or volume.
