AI Technical Summary
In image display devices, due to space or design limitations of driver IC chips, the number of feed lines is limited, making it difficult to improve the signal efficiency and gain of antenna packages. In particular, signal loss is severe in high or ultra-high frequency bands.
An antenna device including first and second antenna units on a dielectric layer is used, which is electrically connected to the first antenna unit through a flexible printed circuit board and electrically separated from the second antenna unit. Auxiliary radiation is added to improve the antenna gain by utilizing the core layer coverage of the flexible printed circuit board and the electric field coupling in the dielectric layer.
Without adding feed lines, the overall gain of the antenna is improved, radiation reliability and signal efficiency in high frequency or ultra-high frequency bands are ensured, and radiation reduction at the side parts or ends of the image display device is prevented.
