A new structure of a circularly polarized dielectric antenna fed by a single coaxial probe is proposed. The configuration includes four identical holes enclosed in a cylindrical resonator. The structure offers a bandwidth of 5% and a good purity of polarization. The effects of altering geometrical parameters on antenna behavior are presented. © 2005 Wiley Periodicals, Inc.

In this paper, we present a new configuration which enhances the impedance bandwidth (we obtain an increase of 80%) and exhibits dual-frequency operation. The characteristics of the new structure are measured and discussed. © 2004 Wiley Periodicals, Inc.

A concept of an original compact dual-band circularly polarized structure antenna is presented. It consists of a dielectric resonator antenna associated with a microstrip one. This antenna has a return-loss bandwidth superior to 6% for each band, and offers in circular polarization a great axial ratio. Such a structure maybe useful for spatial applications. © 2002 Wiley Periodicals, Inc. Microwave Opt Technol Lett 32: 418–420, 2002. [ABSTRACT FROM AUTHOR]

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 FROM AUTHOR]
