Abstract
Hexagonal dielectric resonator antenna (HDRA) for multifrequency operation is proposed and investigated experimentally. The proposed antenna, excited by a single coaxial feed, resonates at four frequencies centered at 2.215, 2.784, 3.445, and 3.955 GHz with identical polarization. The return loss, VSWR, bandwidth, radiation patterns and halfβpower beam width are measured and discussed. Multiple resonances with the same polarization and broad radiation patterns suggest the suitability of the antenna for multifrequency wireless applications. Β© 2006 Wiley Periodicals, Inc.

For the propagating mode, the field is evanescent outside the dielectric. We expect the field to be very small when it reaches the PEC boundary. The difference in higher frequency is because the mesh in SOM is not as dense as that in finite-difference method. ## 4. CONCLUSION In this paper, the wa
band-stop filter can be made more compact by using only one array of SRRs in the ground plane centered under the microstrip line. A study has also been made with regard to the precision of the milling process so as to show that the dimensions of the SRRs play a crucial role in determining the frequ
