TLDR
In this article, a simple model was developed to predict the radiation patterns of the higher-order modes, and rectangular dielectric resonator antennas were designed to operate at high order modes to achieve enhanced gain.Abstract:
Rectangular dielectric resonator antennas were designed to operate at high-order modes to achieve enhanced gain. A simple model was developed to predict the radiation patterns of the higher-order modes. Prototypes designed at 11 GHz showed gains of up to 5 dB above those obtained by the fundamental mode.read more

340 GHz On-Chip 3-D Antenna With 10 dBi Gain and 80% Radiation Efficiency
Abstract: This paper discusses the design methodologies of a 340 GHz on-chip 3-D antenna. Firstly, a high-gain and high-radiation efficiency substrate integrated waveguide (SIW) cavity backed on-chip antenna is designed using a standard 0.13- $\mu{\hbox{m}}$ SiGe BiCMOS technology. Then, a low-permittivity supporter and a dielectric resonator (DR) are vertically stacked on the proposed on-chip antenna, forming a 3-D Yagi-like antenna to further enhance the gain and radiation efficiency. The measurements showed that the proposed antenna achieved a peak gain of ${\sim}$ 10 dBi and radiation efficiency of ${\sim}$ 80% at 340 GHz; the impedance bandwidth is ${\sim}$ 12% with the use of dielectric resonator antenna (DRA) and the Yagi-like structure. The antenna size is ${\sim} {\hbox{0.7}}\times {\hbox{0.7}}\ {\hbox{mm}}^{2}$ .

Book
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.
