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 ...
متن کاملA Compact Dual Band Dielectric Resonator Antenna For Wireless Applications
This paper presents the design of a dual band rectangular Dielectric Resonator Antenna (DRA) coupled to narrow slot aperture that is fed by microstrip line. The fundamental TE111 mode and higher-order TE113 mode are excited with their resonant frequencies respectively. These frequencies can be controlled by changing the DRA dimensions. A dielectric resonator with high permittivity is used to mi...
متن کاملElliptical Dielectric Resonator Antenna for Dual-Band Operation
This paper presents a new dual-band elliptical dielectric resonator antenna (EDRA). The EDRA is mounted on a ground plane and fed with a rectangular slot exited by a microstrip line. By optimizing the structure parameters, it is possible to obtain more than one excited mode in a limited frequency band. Numerical and measurement results for the radiation patterns of this slot fed EDRA are given ...
متن کاملDielectric Resonator Antenna for X band Microwave Application
A simple Dielectric Resonator Antenna (DRA) for X band frequency operation is proposed in this paper. X band is a microwave band lies between frequency range 8 to 12 GHz. In proposed DRA reflector plane is used beneath the microstrip feed line with a small air gap, introduced between feed substrate and reflector plane to reduce the back lobe. Slot coupling is used to excite this DRA. Proposed D...
متن کاملA Wideband High-gain Stacked Cylindrical Dielectric Resonator Antenna
Abstract—A new wideband and high-gain dielectric resonator antenna (DRA) is proposed. Three cylindrical dielectric resonators (DRs) with different materials and different sizes and a metallic cylinder are designed to obtain a wideband bandwidth and a high gain. The stacked structure provides a wideband bandwidth, and the cavity formed by the metallic cylinder provides a high gain. The measured ...
