“…Furthermore, the superior properties of the LTCC technology, such as the potentially high degree of integration, are increasingly losing relevance in modern mm-wave phased array modules not least because of the pervasive use of multi-channel SiGe (Bi)CMOS transceiver chipsets [87], [98]. As a result, the latest module trends for electronically steerable antennas up to the Ka-band are almost exclusively realized with PPE-or PTFE-based dielectric materials albeit the use of low-loss insulator materials such as bis-maleimide & Triazine resins [99] are increasingly gaining momentum in advanced packaging for 5G applications [100].

Satellite, fifth generation (5G), and sixth generation (6G) mobile communication systems operating at micro-and millimeter wave frequencies are an essential pillar in advanced network architectures for high-throughput low latency services. The decisive factors for this current development were the significant technological advances accomplished over the last two decades, which meanwhile enable highly integrated, feature-rich, and cost-effective realizations of complete phased array transceiver topologies. Motivated through the today's trend for heterogeneous constellation types to provide truly global coverage, this contribution reviews the current state-of-the-art of electronically steerable antennas for terrestrial and non-terrestrial communication systems up to 100 GHz. First, the potential benefits and limitations of the most relevant technologies are contrasted and put into context with recent system architectures for adaptive beamforming. Their operating principles along with various experimental implementation and achievements providing advanced capabilities such as multi-band/multi-beam operation, polarization agility, and wideangle scanning are thoroughly presented. Particular emphasis is laid on the review of direct radiating arrays, quasi-optical antenna configurations, and metasurface-based antennas.INDEX TERMS Satellite communications on the move (SOTM), fifth generation (5G), sixth generation (6G), hybrid satellite constellations, aerial networks, electronic steering, phased array, antennas.This article has been accepted for inclusion in a future issue of this journal.

“…The semiconducting materials have identified five major growth applications: (1) mobile, such as smartphones, notebooks, wearables, tablets, etc., [1][2][3][4]; (2) high-performance computing (HPC), which is able to process data and perform complex calculations at high speeds on a supercomputer [5,6]; (3) self-driving cars [7]; (4) Internet Of Things (IOT), such as smart health and smart factories; [3,8,9] and (5) instant data (for edge computing) and big data (for cloud computing) [5,6]. To meet the requirements for boosting signal transmission speed/rate and managing a huge data flood, low-loss (dissipation factor or loss tangent) and permittivity materials are highly preferred [10,11].…”

The aim of this work is to study the effect of various talc rocks for the preparation of talc-based cordierite ceramics. Raw talc and sintered cordierite-based ceramic samples (1000-1375ºC for 2 h) were characterized using XRD, XRF, TGA-DTG, laser PSDs, Archimedes method, SEM-EDAX and dielectric relaxation spectrometer (DRS). Results show that impurity oxide contents, particle size and mineralogical changes of green batches influenced the microstructure densification and crystallization of orthorhombic and hexagonal cordierite. The complex electric modulus plot shows the existence of two relaxation processes associated with the capacitive contribution grain boundaries and grain at low and high frequencies, respectively. The dielectric loss reached much lower values (0.0004–0.0007) for the ceramics composed of higher cordierite phase composition (87.00 to 92.00wt.%) that sintered at 1350 and 1375ºC. Such ceramics could be promising in electronic applications like capacitors, microwave devices and wireless communication.

In this study, the Df (dissipation factor or loss tangent) and Dk (dielectric constant or permittivity) of the low-loss dielectric material from three different vendors are measured by the Fabry–Perot open resonator (FPOR) technique. Emphasis is placed on the sample preparation, data collection, and the comparison with the data sheet values provided from vendors. A coplanar waveguide with ground (CPWG) test vehicle with one of these raw dielectric materials (vendor 1) is designed (through Polar and simulation) and fabricated. The impedance of the test vehicle is measured by TDR (time-domain reflectometer), and the effective Dk of the test vehicle is calculated by the real cross-section of the metal line width, spacing, and thickness of the test vehicle and a closed-form equation. In parallel, the insertion loss and return loss are measured with the VNA (vector network analyzer) of the test vehicle. Finally, the measurement and simulation results are correlated. Some recommendations on the low-loss dielectric materials of the Dk and Df are also provided.
