Abstract

This paper presents a transparent saltwater in glass structure working simultaneously as a UHF antenna and EMI shielding window. The proposed structure has high transparency (> 91%), which is achieved through the use of salt water as a conductive medium held between two clear glass layers, allowing its use as an optical window. On one hand, the saltwater in the glass structure functions as an EMI shielding window, with a shielding effectiveness above 20 dB. On the other hand, the proposed structure works as a transparent UHF antenna by adding only a feeding port.
