“…One comes to the same conclusion when the "dielectric waveguide model" (DWM) method is used to analyze rectangular resonators (481. The presence of the lower-order TM modes was not confirmed experimentally [48]. Therefore, in this section we discuss the lower-order T E modes only.…”

Open dielectric resonators (DRs) offer attractive features as antenna elements. These include their small size, mechanical simplicity, high radiation efficiency due to no inherent conductor loss, relatively large bandwidth, simple coupling schemes to nearly all commonly used transmission lines, and the advantage of obtaining different radiation characteristics using different modes of the resonator. In this article, we give a comprehensive review of the modes and the radiation characteristics of DRs of different shapes, such as cylindrical, cylindrical ring, spherical, and rectangular. Further, accurate closed form expressions are derived for the resonant frequencies, radiation Q-factors, and the inside fields of a cylindrical DR. These design expressions are valid over a wide range of D R parameters. Finally, the techniques used to feed DR antennas are discussed.

Abstract-In this paper, a novel nine elements array dielectric resonator antenna (DRA) is presented. The DRA was excited by a microstrip feeder with a rectangular aperture coupled slots. The slot positions were determined based on the characteristic of standing wave ratio over a short ended microstrip. The measured gain of the array DRA operating at 5.84 GHz was about 10 dBi having impedance bandwidth of 60 MHz. The proposed DRA exhibits an enhancement of the gain in comparison with a single pellet DRA. The size of the whole antenna structure is about 60 mm × 40 mm and potentially can be used in wireless systems.

“…The principles of radiation from the fundamental mode in such a resonator have been reported together with design formula and experimental results [7], [8]. A schematic picture of a rectangular resonator geometry is presented in Figure 2, including a sketch of the electric and magnetic fields of the fundamental mode mirrored in the xz-groundplane.…”

Abstract-Methods to achieve admittance matching of rectangular dielectric resonator antennas intended for 60 GHz impulse radio are reported. The motivation is to find a suitable antenna that may be integrated in the V-band gated tunnel diode wavelet generator, replacing its tank circuit and forming a low complexity transmitter. Probed one-and two-port scattering parameter measurements have been performed to characterise the fabricated antennas. Changing the feed structure from a tapered dipole to an offset fed and tapered slot, a change from capacitive to inductive characteristics is observed, and the matching to the gated tunnel diode is improved. Deembedded admittance resonance frequencies of fabricated antennas were found at 53.6 and 52.2 GHz for dipole and slot fed antennas, respectively. Characterising the transmission link between dipole fed antennas, a maximum antenna gain of 10.5 dBi and a 3 dB power bandwidth of 1.5 GHz were found at 53.3 GHz.
