Summary:
In this paper, the design of the RHCP (right hand circular polarization) dielectric resonator antenna for GPS (Global Positioning Systems) is proposed. For the miniaturization size of antenna, high-permittivity dielectric (εr =30) is used. Also in order to obtain circular polarization of low-profile rectangular dielectric resonator antenna, the proposed antenna is simply excited by single strip line. The proposed single feeding method consisting of a loop shape can easily excite two orthogonal modes (TExδ11,TEyδ11) within the single resonator and easily achieve circular polarization. Using EM simulation, antenna characteristic parameters are found. Based on these results, antenna is manufactured. The simulated and measured results of proposed design are presented.
