Dielectric Resonator Antenna Loaded with Monopole Antenna

2013 Third International Conference on Advanced Computing and Communication Technologies (ACCT), 2013
A DRA loaded with monopole antenna is proposed in the present work. The metal cap is used to cover the monopole antenna top as well as top of DRA. These designing increase the operative frequency of the antenna. The antenna system resonates at 4.4 GHz. The simulation results of return loss, VSWR, gain and radiation pattern are presented.

Elliptical cylinder dielectric resonator antenna

2004 10th International Symposium on Antenna Technology and Applied Electromagnetics and URSI Conference, 2004
Dielectric Resonators (DRs) have many applications as Microwave devices and Antenna. In many DRAs the simple geometry poses a significantly complex electromagnetic fields. There isn't analytical closed-form solution for most but hemispherical DRA. One usual method for the analysis of DRAs is finding propagation modes of its geometry and by knowing the ...

Aperture-coupled dielectric resonator antenna

Antennas and Propagation Society Symposium 1991 Digest, 2002
A practical antenna configuration is proposed for use at microwave and millimeter-wave frequencies. It consists of a circular cylindrical dielectric resonator fed by a microstrip feedline through a coupling aperture in the ground plane between them. Experimental results for antennas operating between 13 and 16 GHz are presented.

Rod-ring dielectric resonator antenna

International Journal of RF and Microwave Computer-Aided Engineering, 2004
A dielectric resonator combining two cylindrical dielectrics of different material and height and excited by a coaxial probe is considered. The effect of the antenna parameters, such as the ratio of the height and radius of the dielectrics and the effect of the probe length, are investigated.
