As the advancement of wireless devices and their applications progress, it is important to produce novel aspects of a usual design to expand their capabilities. One such application could be for extreme circumstances that would include high temperatures. In order to approach this issue, a new substrate has been proposed to implement high-temperature devices. Zirconia Ribbon Ceramic (ZRC) is made of YSZ with high temperature tolerance, smooth surface, moisture resistant, mechanically robust, and low thermal mass properties [1] . Recent publications has demonstrated the suitability of ZRC for implementing functional devices [ 1 –3 ]. Due to this material’s durability and capability of resisting high temperatures, it provides a desirable opportunity of applying this material as a substrate for patch antenna applications. The application of this material, however, requires the understanding of its electrical properties and behavior. This proposed material has a high relative permittivity and a low loss tangent as compared to traditionally available substrates. The high dielectric constant of ZRC along with low loss characteristics allows for realizing efficient wireless systems with smaller form factor. In this study, a wideband patch antenna on ZRC substrate is proposed for high-temperature environments. The antenna operates within 1.89 GHz–3 GHz frequency range, and can be used for WLAN, ISM band, and S-band applications.

RF Characterization of Zirconia Ribbon Ceramic Using T-Resonator Method
Zirconia Ribbon Ceramic (ZRC) is a commercially available ceramic that can be a potential low-loss substrate for radio frequency (RF) devices suitable for high temperatures and harsh environmental conditions. In this paper, the RF characteristics of ZRC are determined in the frequency band of 0.5 GHz to 5 GHz. A T-resonator is designed and fabricated for the transmission coefficient measurements to obtain complex permittivity (dielectric constant and loss tangent) values of the material. The dielectric constant is shown to be steady at 32.2, while the loss tangent is found to be at 0.001 in the band of interest.

This article provides a broadband dielectric characterization of different silicate substrates up to 115 GHz, to fill the gap in the properties of different kinds of glasses in a broad part of the mm-wave spectrum. Both the internal structure (crystalline or amorphous) and the chemistry of the substrates influence the permittivity and loss tangent of the material. Quartz and sapphire are crystalline materials that exhibit a low loss in the mm-wave frequency range. Amorphous silicates generally have higher loss values than crystalline materials, and within the glasses, the level of impurities added also affects the dielectric loss. Several characterization techniques have been employed to cover a broad frequency band. The limitations of the different characterization techniques are also included. Once the dielectric properties of substrates are characterized, a metasurface has been designed and fabricated at 100 GHz to increase the reflection in window glass and provide coverage on areas that would otherwise be shadowed. The measurement results are in good agreement with the simulations.more » « less

In this paper, a Multi-Input Multi-Output (MIMO) antenna of 4 monopole elements is presented on Zirconia Ribbon Ceramic (ZRC) substrate. Utilization of this substrate material allows an implementation of an antenna system that is able to withstand harsh environments and high temperatures due to inherent substrate characteristics. The proposed MIMO design supports an operational antenna bandwidth from 2.44 GHz to 2.55 GHz with a center frequency around 2.5 GHz covered by all 4 antenna elements. High antenna isolation below -15 dB is obtained among the ports. The antenna also provides a peak gain over 3 dB through the entire band of interest (3.34 dB at 2.5 GHz) and low cross-polarization.more » « less

We report on the dielectric response of epitaxial BaSnO3 films grown on Nb-doped SrTiO3 (001) substrates using a hybrid molecular beam epitaxy approach. Metal-insulator-metal capacitors were fabricated to obtain frequency- and temperature-dependent dielectric constant and loss. Irrespective of film thickness and cation stoichiometry, the dielectric constant obtained from Ba1−xSn1−yO3 films remained largely unchanged at 15-17 and was independent of frequency and temperature. A loss tangent of ∼1 × 10−3 at 1 kHz < f < 100 kHz was obtained for stoichiometric films, which increased significantly with non-stoichiometry. Using density functional theory calculations, these results are discussed in the context of point defect complexes that can form during film synthesis.more » « less

Microfluidically reconfigurable radio-frequency (RF) devices in general have been found attractive for low-loss, wide-frequency tunability and high-power-handling capabilities. Recently, integrated actuation of the microfluidically reconfigurable devices has been proposed for compact mm-wave device applications. This article for the first time introduces microfluidically reconfigurable frequency- and/or bandwidthtunable bandpass filters (BPFs) operated at the mm-wave band with integrated actuation. The BPFs consist of coupled hairpin resonators. Frequency tuning is achieved by capacitively loading the resonators. Bandwidth tuning is achieved by creating varying capacitive loading among the resonators to control the interresonator couplings. The capacitive loading mechanisms are realized using the selectively metallized plates (SMPs) that can be repositioned within the microfluidic channels. The microfluidic channels are located directly above the stationary metallizations of the filter. Piezoelectric bending actuators placed under the filter’s ground plane provide the SMP motion capability. The BPFs perform with the worst-case insertion loss of 3.1 dB. Frequency-tuning capable filters operate within 28–38-GHz band. Fractional bandwidth tunability varies from 7.8% to 16.7% at 38 GHz and 7.6% to 12.5% at 28 GHz for the filter that is capable of both tuning mechanisms. The filters are characterized to handle 5 W of the continuous RF power without needing thick ground planes or heat sinks. In addition, the frequency-tuning speed is characterized to be 285 MHz/ms.more » « less
