band-stop filter can be made more compact by using only one array of SRRs in the ground plane centered under the microstrip line. A study has also been made with regard to the precision of the milling process so as to show that the dimensions of the SRRs play a crucial role in determining the frequ

Abstract
A dual‐frequency cylindrical dielectric resonator antenna is presented. This paper proposes a configuration in which the shape and volume of the radiating structure remain unchanged. The behaviour of this antenna after altering some of its attributes is investigated. © 2003 Wiley Periodicals, Inc. Microwave Opt Technol Lett 38: 9–10, 2003

## Abstract In this paper, a dielectric resonator antenna for dual‐frequency operation is proposed. The proposed antenna is excited by dual 50Ω microstriplines and printed in a single metal layer, and therefore is easily constructed. In this design, the operating frequency is mainly controlled by t
## Abstract Two feeding designs for achieving dual orthogonal linear polarization operations of dielectric resonator (DR) antennas fed by microstrip lines are demonstrated. The microstrip feedlines can be placed directly under the DR or conformal to the surface of the DR. Good dual‐polarization exc
## Abstract Design of a microstrip‐line‐feed slot‐coupled cylindrical dielectric resonator antenna (DRA) for circular polarization (CP) is investigated experimentally. The occurrence of the two orthogonal near‐degenerate resonant modes is mainly excited by a perturbed annular slot that is, a C‐shap
## Abstract A dual and wideband single‐element rectangular dielectric resonator antenna (DRA) excited by a microstrip aperture is investigated experimentally. It provides two passbands in the ranges of 2.21–2.855 GHz and 4.385–5.455 GHz, which are popular bands for wireless local‐area networks (WLA
## Abstract This paper presents a new wideband dielectric resonator (DR) antenna. To enhance the bandwidth, two layers of stacked resonators having the same rotational axis of symmetry are used. At the bottom layer, a smaller cylindrical DR is placed concentrically inside a large annular‐ring DR, w
