A Cuboid Dielectric Resonator Antenna fed by microstrip feed line is studied. The dielectric resonator of the antenna is made by a material with high dielectric constant ∊r=30. The impedance matching of dielectric resonator can be improved by using a # slot in the ground. In additional, a two elements array is used to enhance the performance of the antenna. This proposed antenna is suitable for long-term...
This paper designs an ultra-broadband absorber based on tightly coupled array (TCA), whose reflectance coefficient is expected to be below −10dB from 2.43GHz to 16.65GHz theoretically. It is found that the TCA absorbers are ultra-wideband, low-cost, low-profile, and conformable. The results of theory and simulation are given.
This paper presents the findings of a steerable higher order mode (TE$^{\mathrm {y}}_{1\delta 3}$ ) dielectric resonator antenna with parasitic elements. The beam steering was successfully achieved by switching the termination capacitor on the parasitic element. In this light, all of the dielectric resonator antennas (DRAs) have the same dielectric permittivity similar to that of ten and excited...
In this paper, a V-band low sidelobe and wideband series fed linear dielectric resonator antenna (DRA) array is proposed. Among many kinds of DRAs, the perforated rectangular dielectric resonator antenna (RDRA) is chosen as the antenna element in our design, which can enhance the impedance bandwidth by lowering down the quality factor. By optimizing the size of the slots and distance between adjacent...
In this paper, the design of aperture-couplet rectangular dielectric resonator antennas arrays is illustrated. The effect of slot feed on the dielectric resonator antenna (DRA) and the effect of the spacing between array elements is observed. This paperwork can be useful for WLAN applications with the operating frequency 5.8 GHz.
