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 provides complete, up-to-date details on DRAs in a single volume, including: Clear guidance on the mode of operation and radiation behavior of DRAs; Details on methods of excitation; Descriptions of major advances in DRA technology; Simple equations and graphs that aid in the rapid design of spherical, cylindrical, and rectangular DRAs; Guidelines for designing feeds required to excite DRAs, such as probes, apertures, and microstrip lines; Techniques for enhancing the bandwidth performance of DRAs for wideband applications; Assistance in designing low-profile DRAs and DRAs with circular polarization; Approaches for designing linear and planar DRA arrays; Advice on the fabrication of DRAs and measurement methods used to characterize their performance; Numerous design examples illustrating the versatility of DRAs.
