Silicate ceramics are of considerable promise as high frequency dielectrics in emerging millimetre wave applications including high bandwidth wireless communication and sensing. In this review, we show how high quality factors and low, thermally stable permittivities arise in ordered silicate structures. On the basis of a large number of existing studies, the dielectric performance of silicate ceramics is comprehensively summarised and presented, showing how microstructure and SiO4 tetrahedral connectivity affect polarizability and dielectric losses. We critically examine the appropriateness of silicate materials in future applications as effective millimetre wave dielectrics with low losses and tuneable permittivities. The development of new soft chemistry based processing routes for silicate dielectric ceramics is identified as being instrumental towards the reduction of processing temperatures, thus enabling silicate ceramics to be co-fired in the production of components functioning in the mm wave regime.

“…We can find that the boundary conditions of DRA will change in two different cases. By adjusting position and width of these transparent conductive strips, the appropriate mode is manipulated to improve the impedance bandwidth and gain 23 . The transparent conductive strips used in this article is a common electromagnetic shielding film SSP‐100 with a transparency of about 80% and a tested surface resistance of 0.12 Ω/cm 2 .…”

This article presents a compact hybrid solar and radio frequency (RF) energy harvester based on dual-band transparent dielectric resonator antenna (TDRA). It integrates with an amorphous silicon solar cell film, a TDRA and a rectifier circuit. The TDRA replaces the glass protective of the traditional solar cell to prevent the solar cell from being oxidized and damaged and also can efficiently harvest electromagnetic (EM) waves, which achieves harvesting solar and RF energy at the same time. The measured results show that the TDRA can reach impedance bandwidth (jS11j < À10 dB) of 2.37-3.03 GHz and 3.41-3.88 GHz and the realized gain of 4.9 dBi at 2.45 GHz and 5.95 dBi at 3.6 GHz. The efficiency of the rectifier can reach 60% and 40% at two resonance frequencies, respectively. The results prove that under weak lighting conditions, the hybrid harvester has a higher DC output power compared with the RF-only or solar-only energy harvester. Thus, it can be well applied to wireless sensors and Internet of Things devices.

“…The proposed antenna configuration is stacked DRAs, even though the proposed antenna size is less comparative to other research articles, 9,11,12,17,20,[22][23][24][25] it is worth mentioning that there are various methods to reduce the size of antenna. [31][32][33][34][35] The simplest way to design a compact size DR, is to select high dielectric constant material. The drawback of using high dielectric constant material is it has high-quality factor and thus reduces overall bandwidth of the antenna.…”

In this paper, two identical Cylindrical Dielectric Resonator Antennas (CDRA) are stacked together to achieve Circular Polarization (CP). Ultra wideband impedance bandwidth and wide axial ratio bandwidth is achieved by three factors: stacking of similar DRs, stepped conformal microstrip feed line which will generate orthogonal modes and new partial ground plane with circular rings. Measurement results show that the proposed stacked Cylindrical CPDRA achieves an Impedance Bandwidth (IBW) of (S11 < −10 dB) of 72.48% (3.65–7.8 GHz) and Axial Ratio Bandwidth (ARBW) (AR <3 dB) of 44.12% (4.38–6.86 GHz), respectively. In addition, the proposed antenna shows dominant Left Hand CP with gain ranges from 1.4 to 6.5 dBic with maximum radiation efficiency of 93.3%. The advantages and novel points of proposed research work is as follows: (i) The novel configuration of stacking CDRA's along with stepped microstrip feed enhances ARBW, (ii) New proposed partial ground plane with two circular rings provides enhancement in IBW, (iii) Simple design and small height of DRs produces enhanced IBW, ARBW, Gain and Efficiency. Furthermore, by changing the position of circular rings on ground plane, the proposed antenna provides dominant LHCP to RHCP conversion and achieves polarization reconfigurability. The proposed antenna configuration covers the frequency range of applications of C‐band and military satellite communication.
