Title:
DISPLAY COVER FOR WIRELESS TERMINAL
Document Type and Number:
WIPO Patent Application WO/2023/002612
Kind Code:
A1
Abstract:
The present invention provides a display cover for a wireless terminal that suppresses a decrease in antenna performance of the wireless terminal even when arranged on a display, and that can amplify electric waves of the antenna that uses the direction in which the display is arranged as the main radiation direction. This display cover for a wireless terminal is arranged on the display of a wireless terminal formed in a plate shape. This display cover for a wireless terminal comprises: a sheet-shaped transparent member arranged so as to be superimposed on the display and formed using a transparent dielectric in which the relative dielectric constant is in the range of 1-10; and a plurality of conductive elements arranged side by side on the transparent member, the visible light transmittance of the conductive elements being 50% or greater. The conductive elements are formed such that the length of the longest line segment, which is the longest among the line segments formed on the conductive element by connecting any two points on the conductive element, is in the range of 0.1-0.04 times the length of the effective wavelength in the dielectric of the electric wave used for wireless communication by the wireless terminal.
