The higher order resonant mode (HEM12δ), in a cylindrical dielectric resonator antenna (CDRA) has been investigated in regards to using it for practical purposes. In this paper, we have addressed the effect of the dielectric permittivity and other antenna parameters on the impedance and radiation characteristics. The HEM12δ mode is excited using a non resonating microstrip patch. © 2012 IEEE.

Investigation of a cylindrical dielectric resonator antenna excited with a higher order mode

IEEE Antennas and Propagation Society, AP-S International Symposium (Digest)

A resonant mode (HEM 12δ), other than those (HEM 11δ and TM 01δ) conventionally excited and used in a cylindrical dielectric resonator antenna (CDRA) has been examined with a view for using it as another radiating mode with broadside radiation patterns. Excitation of the mode, being the most challenging aspect, has been discussed and resolved by employing an innovative technique. The proposed concept has been successfully verified and experimentally demonstrated for the first time. More than 8-dBi peak gain with excellent broadside radiation has been obtained from a prototype shaped from a commercially available low-loss dielectric material with relative permittivity 10. © 2006 IEEE.

Higher order mode excitation for high-gain broadside radiation from cylindrical dielectric resonator antennas

HEM 11δ mode is commonly used in Cylindrical Dielectric Resonator Antenna (CDRA) for broadside radiation. Very recently the present authors have been successful in exciting the higher order mode (HEM 12δ), which is equally suitable for broadside radiation. The higher order mode suffers from limitations compare to the dominant (HEM 11δ) mode. A comparative study in terms of antenna parameters and feed has been presented in here. © 2011 IEEE.

Limitations in proper excitations of HEM 11Î´ and HEM 12Î´ modes in a Cylindrical Dielectric Resonator Antenna: A comparative study

HEM12δ mode has been recently excited successfully in a CDRA by the present authors. This is with high gain broadside radiation characteristics. In this paper, we have examined the limitations of the newly proposed feeding mechanism and possibility of using this mode for practical purpose. © 2011 IEEE.
