A 5G base station antenna array with a frequency selective surface (FSS) radome is designed. The consists of 1 mm thick metal layer and 2.2 dielectric layer. can effectively radiate within the operating band suppress out-of-band interference due to utilization FSS. More importantly, FSS in direct contact reflector, enabling efficient conduction heat from interior outside, thereby improving station’s dissipation capability. To validate applicability designed heatsink station, 1×4 also...

A novel anionic surfactant-templated synthesis of ZnO/mesoporous silica nanocomposites has been carried out by using N-hexadecylethylenediamine triacetate (HED3A), a triprotic surfactant, as the structure-directing agent. The chelating template can capture zinc ions in solution and then direct mesophase formation, enabling an amount oxide to be embedded porous matrix during calcination. With variation molar ratio Zn(2+) HED3A template, series composites with different doping amounts were...

A facile in situ approach has been designed to synthesize zinc ferrite/mesoporous silica guest-host composites. Chelating surfactant, N-hexadecyl ethylenediamine triacetic acid, was employed as structure-directing agent fabricate mesoporous skeleton and simultaneously complexing incorporate stoichiometric amounts of iron ions into cavities. On this basis, spinel ferrite nanoparticles with grain sizes less than 3 nm were encapsulated channels after calcination. The mesostructure, meanwhile,...

This work focused on the preparation of poly (vinyl alcohol) (PVA)/ layered double hydroxide (LDH) and LDHSA nanocomposites by casting method. The morphology interlayer spacing composites were characterized. mechanical properties photochemical stability film PVA, PVA/LDH PVA/LDHSA have been studied compared with PVA/MMT reported in previously. results indicated that thermal dynamic PVA matrix films was enhanced. PVA/OMMT shown stable photochemically more than those pure PVA.
