A novel high-gain dielectric resonator antenna (DRA) for wideband wireless applications is presented. The antenna is composed of a hollow cylindrical dielectric resonator (DR) inside which an assembly of two dielectric truncated cones having different permittivities are inserted. A suitable probe excitation system and an air gap, realized between the base of the first truncated dielectric cone and the ground plane, are used to further increase the antenna bandwidth. A full-wave commercial software based on the finite integration technique (FIT) has been used to analyze and design the antenna, while the singularity-extraction method (SEM) has been adopted to extract information about the main resonant processes taking place in the proposed radiating structure.read more

Using the matrix pencil method to estimate the parameters of a sum of complex exponentials
Tapan K. Sarkar,O. Pereira +1 more
TL;DR: The matrix pencil method is described, which is more robust to noise in the sampled data and has a lower variance of the estimates of the parameters of interest than a polynomial-type method, and is also computationally more efficient.

Dielectric resonator antenna handbook
Abstract: In recent years, the dielectric resonator antenna (DRA) has emerged as a new and viable alternative to conventional low-gain elements such as dipoles, monopoles, and microstrip patches. This practical resource presents complete, up-to-date details on DRAs in a single volume. The book provides you with clear guidance on the mode of operation and radiation behavior of DRAs, the main methods of excitation, and the major advances in DRA technology. This hands-on reference equips you with simple equations and graphs that help you rapidly design DRAs of spherical, cylindrical, and rectangular shapes, without having to resort to complex analytical or numerical calculations. You find guidelines for designing feeds required to excite the DRAs, such as probes, apertures, and microstrip lines. In addition, the book offers you various techniques for enhancing the bandwidth performance of DRAs for wideband applications. You learn how to design low profile DRAs and DRAs with circular polarization. Several approaches for designing linear and planar DRAs arrays are also considered. Moreover, this comprehensive book provides advice on the fabrication of DRAs and measurement methods used to characterize their performance. Numerous design examples are included to give you a sense of the versatility that DRAs afford.
