Recently, the Dielectric Resonator Antenna (DRA) radiating element has been the subject of considerable interest due to its small size and high efficiency. The rigorous analysis of DRA elements, however, has been largely restricted to rotationally symmetric shapes. Other shapes have been analyzed, however, often based on an infinite ground plane assumption which restricts the use of the DRA as a single element for some applications that require finite size ground plane. Various numerical techniques have been used in the analysis of the DRA. The spherical mode expansion was used to analyze a hemispherical DRA. The Surface Integral Equation with the Method of Moments (SIE/MoM) has been used to analyze a rotationally symmetric DRA. The modal expansion method with some approximation was used in to analyze the rectangular DRA, and the Finite Difference Time Domain (FDTD) method has been used to analyze a rectangular DRA and cylindrical DRA with a staircased cell approximation. Here the rectangular DRA is considered over a finite ground plane with a microstrip slot excitation. The SIE/MoM is used with the RWG triangle basis function expansion. Using the triangle basis functions allows modeling of arbitrarily shaped objects. Also, the FDTD method is used to analyze the same problem for the purpose of verifying both methods. The effect of the ground plane size and the dielectric substrate truncation is studied.

Today, more and more antenna engineers are viewing the Dielectric Resonator Antenna (DRA) as a preferable alternative to conventional low-gain designs because of several attractive features, including high radiation, light weight, small size and low profile. This practical resource presents complete, up-to-date details on DRAs in a single volume. The book provides professionals 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 engineers with simple equations and graphs that help them rapidly design DRAs, without the need for complex analytical or numerical calculations. Numerous design examples are included to give practitioners a sense of the versatility that DRAs afford.

Up-to-date coverage of the analysis and applications of coplanar waveguides to microwave circuits and antennas The unique feature of coplanar waveguides, as opposed to more conventional waveguides, is their uniplanar construction, in which all of the conductors are aligned on the same side of the substrate. This feature simplifies manufacturing and allows faster and less expensive characterization using on-wafer techniques. Coplanar Waveguide Circuits, Components, and Systems is an engineer's complete resource, collecting all of the available data on the subject. Rainee Simons thoroughly discusses propagation parameters for conventional coplanar waveguides and includes valuable details such as the derivation of the fundamental equations, physical explanations, and numerical examples. Coverage also includes: Discontinuities and circuit elements Transitions to other transmission media Directional couplers, hybrids, and magic T Microelectromechanical systems based switches and phase shifters Tunable devices using ferroelectric materials Photonic bandgap structures Printed circuit antennas
