چکیده
In this paper effects of coaxial probe feeding position and its penetration inside the radiating structure of an antenna has been presented in detail. For this purpose, a Rectangular Dielectric Resonator Antenna (RDRA) has been synthesized and analyzed. There effects on the characteristic behavior of antenna have been obtained. Optimized condition is established and relation between probe dimensions and probe separation from the axial point of DR has been sorted out upon which the characteristics of the RDRA such as bandwidth, radiation pattern and gain of antenna depend. Parametric variations of different parameters for the RDRA are simulated and bandwidths exceeding 45% is achieved. Theoretical performance of the antenna is verified by full-wave simulations and experimental data obtained from a prototype. The obtained performance of proposed design, confirms the practicability of antenna in different indoor/outdoor wireless applications.

Numerical Modeling and Experimental Study of Probe-Fed Rectangular Dielectric Resonator Antenna (RDRA) Supported by Finite Circular Ground Plane
Dielectric Resonator Antennas (DRAs) have received increased interest in recent years for their potential applications in microwave and millimeter wave communication systems. DRAs are normally used with the support of a ground plane. The radiation and impedance properties therefore depend not only on their physical dimensions and dielectric properties, but also on the size of the ground plane. ...

A new shaped circularly polarized dielectric resonator antenna (CP DRA) is studied with branch-line coupler and log-periodic balun for the GPS application. Since the coupler and balun are located under the DRA, it does not increase the footprint of the antenna, as a result the system is very compact. Two configurations are considered in this paper. In the first configuration, an external 50Ω lo...
