Bandwidth Enhancement for Split Cylindrical Dielectric Resonator Antennas

Bandwidth Enhancement Techniques of Dielectric Resonator Antenna

The paper briefly reviews the historical background of dielectric resonator antenna and its bandwidth enhancement techniques. The main focus is on a compact DRA that can offer broad band operation. It has been illustrated that dual resonance and multi resonance operation can be much effective to give wide band characteristics of DRA. Index Terms dielectric resonator antenna, broadband, multi re...

Integrated Ultra-wideband Plannar Monopole with Cylindrical Dielectric Resonator Antennas

Abstract—An ultra-wideband (UWB) planar monopole antenna integrated with a narrow-band (NB) cylindrical dielectric resonator antenna (DRA) is presented. The proposed antenna consists of a UWB monopole excited by a coplanar waveguide (CPW) transmission line, acting as a ground for a DRA excited by a slot. The mode HEM11δ is excited in the NB DRA. To validate the concept of integration, an antenn...

Probe-Fed Rectangular Dielectric Resonator Antennas,Theoretical Modeling and Experiments

A Rectangular Dielectric Resonator Antenna (RDRA) is theoretically analyzed using the Conventional Dielectric Waveguide Model (CDWM), numerically simulated using the High Frequency Structure Simulator (HFSS) based on the Finite Element Method (FEM) software package and experimentally investigated with the consideration of the fundamental mode TE 111. Antenna parameters under investigation inclu...

Embedded Dual band Cylindrical Dielectric Resonator Antenna

A compact dual-band antenna made of high dielectric constant substrate is studied. Embedding a higher dielectric cylindrical inside the substrate host cylindrical enhances the dual-band behaviour. The first part displays the characteristics of single CRDA as return loss, bandwidth and radiation pattern, then, the second part describes the aim of using an antenna, composed by the arrangement of ...
