“…Open dielectric resonators are potentially useful antenna elements [1]. They offer several attractive features such as small size, high radiation efficiency [1][2][3], compatibility with MIC's, intrinsic mechanical simplicity, and the ability to obtain different radiation patterns using different modes. Many of the concepts used in the design of microstrip antennas can also be used in the design of dielectric resonator antennas.…”

Abstract-In this paper the classical boundary value approach employing the separation of variable technique is used to analyze the properties of elliptic dielectric resonator antennas. In this approach, the fields inside the resonator are expanded in terms of Mathieu and modified Mathieu functions. Numerical results are given for resonant frequencies of different modes as well for fields distribution inside the resonator. Series Green's functions are used to calculate the fields inside the cavity and also far field patterns for a given feed. Using the Green's function method provides more accurate results compared to a pure cavity model technique. The analysis and design are verified through numerical simulations. A parametric study has been performed to show effects of the elliptical dielectric resonator antennas (EDRAs) parameters on far field patterns.

“…Several developments of Wheeler's idea consecutively enhanced its precision. Beyond the equivalent circuit employing loss and radiation resistances, two wellknown algorithms are the generalized Wheeler Cap method [7] and the Quality factor method [8,9]. The key concept of these techniques is to compensate for inaccuracies due to resonating modes of the shielding cavity.…”

Abstract-A new equivalent circuit based Wheeler Cap method to calculate MIMO efficiency is introduced. The method works without the necessity for interpolation by avoiding concur of resonating and cavity modes. The method is tested with a set of three differently correlated MIMO antennas. Results are compared with the recently proposed quality factor method for MIMO antennas and efficiency data from spherical near field measurements.
