In this paper, a wideband metal-line antenna for $\\mathbf{5 G}$ metal frame mobile phones is proposed and analyzed. The proposed antenna consists of a T branch and two ground branches, an SP5T switch ...

During annealing, dehydroxylation proceeds gradually, leading to the formation of metal–organic dimers, tetramers, and extended chains. Notably, thermal treatment at 530 K triggers C–H activation of ...

A novel Long Term Evolution (LTE) antenna design for mobile phones with metal frame is proposed. In particular, in this design only the metal frame acts as the antenna radiating element, and the ...
