A wideband cylindrical dielectric resonator antenna (CDRA) is presented in this paper, which has a simple structure and is fed by the aperture coupling feeding method. Both the substrate and the dielectric resonator (DR) are made of new material whose relative permittivity is inversely proportional to the frequency square. Since the size of the dielectric resonator antenna (DRA) is proportional to the wavelength (at the resonant frequency) over square root of the permittivity. Therefore, the size of the DRA will not change with the resonant frequency. The resonant frequency will be determined and controlled by the feeding structure. During this process, the mode excited will keep the same. In addition, compared with the traditional DRA, the proposed DRA has a compact size and wider impedance bandwidth by employing the new material.
