摘要：
In this paper, we study a Dielectric Resonator Antenna of cylindrical shape with circular polarization for applications in the C band. The proposed antenna is composed of two different layers. The first is Polyflon Polyguide with relative permittivity epsilon(r1) = 2.32 and a loss tangent tan delta = 0.002 as a lower layer. The second is Rogers RO3010 with relative permittivity epsilon(r2) = 10.2 and a loss tangent tan delta = 0.0035 as an upper layer which is excited by dual probe feed. The 90 degrees phase shift of two probes feed can create a circular polarization. In this study, we focused on the effect of the variations in the height of the Polyflon Polyguide as well as the probe feed. Simulations under HFSS software have led to bandwidth values of about 2.2 GHz and 2.6 GHz for the proposed antenna with one probe and dual probe, respectively. The obtained gains are higher than 5.4 dB and can range up 8.1 dB.
