In this article, we propose a conical dielectric resonator antenna with metamaterial operating in the C band and excited by a circular polarization. The circular polarization of the antenna is produced by an inclination of 45° on the two environments with a different dielectric constant of the slot excitation. The metamaterial is superimposed on the antenna by
and thus allows to increase the gain...
In this paper, a multilayer conical dielectric resonator antenna (DRA) excited by two coaxial cables has been investigated. The phase shift of the two coaxial cables with 90° creates a circular polarization of the radiated electromagnetic wave. The proposed structure provides a bandwidth of about 41% with a gain ranging from 4.8 dB to 8.7 dB in the bandwidth. The simulation study of the proposed antenna...
In this paper, we propose a dual layer conical Dielectric Resonator Antenna (DRA) excited by a slot. The inclination of the two environments with different dielectric constants relative to the slot can create a Circular Polarization (CP). Simulations performed under Ansoft HFSS software show that the proposed conical shaped DRA is circularly polarized and can reach a large bandwidth of 1.14 GHz with...
