“…The demand for MLCCs has outstripped the supply for many years now, leading to increasing lead times and prices for many consumer electronics. The compositional diversity of silicate ceramics offers the possibility to tailor the dielectric properties of material systems to individual applications [30]. In an industrial context, dielectric antennae [31] or antenna-lens combinations [32] offer the possibility to shape radiated beam profiles according to system needs.…”

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.

“…The technology realisation is increasingly relying on continuously tunable liquid crystals (LC) [7][8][9] based mm-Wave beam steering flat-panel [10] antennas array (static and fault-tolerant), in place of the conventional parabolic dishes [11] with a mechanically rotating mechanism (bulky and maintenance-intensive). The recent decade has witnessed a significant boost in long-range automotive radars at 76-81 GHz [12] with a threefold increase in resolutions than the traditional 24 GHz ones [13], though costs reduction remains challenging for a wider commercialisation. As an enabler for amplitude and phase control of mm-Wave signals, LC-based phase-shifting solution has been on industrial and academic research's radar as one of the cost-effective answers for such high-accuracy-oriented beam-steering applications.…”

Unconventional folded shielded coplanar waveguide (FS-CPW) has yet to be fully investigated for tunable dielectrics-based applications. This work formulates designs of FS-CPW based on liquid crystals (LC) for electrically controlled 0-360˚ phase shifters, featuring a minimally redundant approach for reducing the LC volume and hence the costs for mass production. The design exhibits a few conceptual features that make it stand apart from others, noteworthy, the dual-strip structure with a simplified enclosure engraved that enables LC volume sharing between adjacent core lines. Insertion loss reduction by 0.77 dB and LC volume reduction by 1.62% per device are reported at 77 GHz, as compared with those of the conventional single-strip configuration. Based on the proof-of-concept results obtained for the novel dual-strip FS-CPW proposed, this work provides a springboard for follow-up investible propositions that will underpin the development of a phased array demonstrator.

“…The antennas used on the LTCC substrates have been widely investigated in the past few years and a couple of radar sensors based on this technology have been presented [11–15]. In this contribution, the feasibility of a MIMO LRR with the desirable narrow beam in elevation ( H ‐plane) and wide beam in Azimuth ( E ‐plane) is investigated.…”
