Journal ArticleDOI
Dielectric resonator antennas—a review and general design relations for resonant frequency and bandwidth
R.K. Mongia,Prakash Bhartia +1 more
TL;DR: In this paper, a comprehensive review of the modes and the radiation characteristics of open dielectric resonators (DRs) of different shapes, such as cylindrical, spherical, and rectangular, is presented.
Book
RF and microwave coupled-line circuits
TL;DR: In this paper, the authors present a theoretical analysis of planar transmission lines with parallel-coupled TEM Directional Couplers and tight couplers, as well as Coupled-Line Filter Fundamentals.
Patent
Broadband nonhomogeneous multi-segmented dielectric resonator antenna system
TL;DR: In this paper, a dielectric resonator antenna system is described, where a high-dielectric constant material is placed between a DRA and the antenna feed to enhance the coupling.
Journal ArticleDOI
Low profile dielectric resonator antennas using a very high permittivity material
TL;DR: Low profile rectangular dielectric resonator antennas, fabricated out of a very high permittivity material ( epsilon /sub r/=100), were reported in this paper. But their performance was limited to 3% bandwidth.
Journal ArticleDOI
Measurement of radiation efficiency of dielectric resonator antennas
TL;DR: In this article, the authors measured the radiation efficiency of dielectric resonator antennas in the dominant hybrid (HE/sub 11/spl delta) mode and showed that the conduction losses are quite small.
