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 ...

Design of Hollow Cylindrical Dielectric Resonator Antenna Excited By Micro-strip Lines

Objective of this study is to enhance radius of curvature of return loss, input impedance & explore SWR and radiation pattern. Hollow CDRA has been used instead of single-element CDRA to achieve the above mentioned goal. The impedance bandwidth of a high permittivity hollow cylindrical dielectric resonator antenna excited by micro-strip lines was significantly improved by modifying the feed geo...

Broadband Slot Cut Modified Rectangular Microstrip Antenna

The broadband microstrip antenna is realized by cutting a slot at an appropriate position inside the slot. The slot introduces a mode near the fundamental resonance frequency of the patch and realizes broadband response. The broadband patch antenna is also realized by using the proximity feeding technique. Using substrate of thickness greater than 0.080, the bandwidth of slot cut patch antenna...

A Cylindrical Dielectric Resonator Antenna for Wireless Body Area Networks

In this paper, a hybrid dual-band cylindrical dielectric resonator antenna with parasitic slot fed by a microstrip line that is suitable for wireless body area network is proposed. In this configuration, the dielectric resonator performs the functions of an effective radiator along with the feeding structure and the slot in the ground plane.
