30°-60°-90° Triangular Dielectric Resonator Antenna: A new shaped Dielectric Resonator Antenna

2016 IEEE 7th Annual Information Technology, Electronics and Mobile Communication Conference (IEMCON), 2016
30°-60°-90° triangular shaped Dielectric Resonator Antenna (DRA) is investigated here. The DRA is formed by cutting the equilateral Triangular DRA (TDRA) along its median. Fundamental mode is excited for both antennas. A comparative study between input impedance, S 11 and far-field power patterns are presented.

Impact of Infill Pattern on 3D Printed Dielectric Resonator Antennas

IEEE Asia-Pacific Conference on Antennas and Propagation, 2018
This paper studies the impact of different infill patterns on 3D printed dielectric resonator antennas (DRAs). Different infill patterns with the same infill percentage setting can have very different actual material infill percentages, which can result ...

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 ...
