Abstract
Official abstract text for this publication.
An antenna device includes a dielectric layer and a radiation electrode on an upper surface of the dielectric layer. The radiation electrode includes a plurality of electrode lines therein. The radiation electrode has a visibility index in a range from −1.4 to 1.9. An electrode visibility is suppressed and a signaling sensitivity is enhanced from the radiation electrode. A display device including the antenna device is also provided.
First claim
Opening claim text (preview).
What is claimed is: 1. An antenna device, comprising: a dielectric layer having a first surface and a second surface opposite to the first surface; and a radiation electrode on the first surface of the dielectric layer, the radiation electrode comprising a plurality of electrode lines, the radiation electrode having a visibility index in a range from −1.4 to 1.9, the visibility index being defined as Equation 1: Visibility Index=Log(contrast×contrast sensitivity function (CSF) value). [Equation 1] 2. The antenna device according to claim 1 , wherein the CSF value in Equation 1 is calculated from Equations 2, 2-1 and 2-2 below: CSF ( L , f ) = a ( L , f ) fe - b ( L ) f ( 1 + 0.06 e b ( L ) f ) 0.5 [ Equation 2 ] a ( L , f ) = [ 540 ( 1 + 0.7 / L ) - 0.2 ] [ 1 + 12 ( 1 + f / 3 ) - 2 / w ] [ Equation 2 - 1 ] b ( L ) = 0.3 ( 1 + 100 / L ) 0.15 [ Equation
