Embodiment Construction

[0052] In the present disclosure, it will be understood that when an element or layer is referred to as being "on," "connected to," or "coupled to" another element or layer, the element or layer A layer may be directly on, directly connected to, or directly coupled to the other element or layer, or intervening elements or layers may be present.

[0053] The same reference numerals denote the same elements throughout. In the drawings, thicknesses, ratios, and sizes of components may be exaggerated in order to effectively describe technical contents.

[0054] As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0055] It will be understood that although the terms first, second, etc. may be used herein to describe various elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be constrained by limitations of these terms. These terms are only us...

Abstract

The invention relates to a radio frequency device, a radio frequency antenna and a display device. The display device includes a display panel, a conductive layer disposed on the display panel and including a plurality of first patterns and a plurality of second patterns having a shape different from the first patterns, and an antenna element spaced from the conductive layer and operating in each of a first frequency band and a second frequency band. A first signal within the first frequency band constructively interferes with a first reflected signal corresponding to the first signal reflected at least partially by the first patterns, and a second signal within the second frequency band constructively interferes with a second reflected signal corresponding to the second signal reflected at least partially by the second patterns.

Description

[0001] Cross References to Related Applications [0002] This patent application claims priority from Korean Patent Application No. 10-2020-0032990 filed on March 18, 2020, the contents of which are hereby incorporated by reference in their entirety. technical field [0003] The present disclosure relates to a radio frequency (RF) device capable of broadband communication, and more particularly, to a display device including the radio frequency device. Background technique [0004] The display device includes circuitry arranged in an electronic module. Such a display device may be a portable terminal or a wearable device in which an electronic module includes an antenna module, a camera module or a battery module. With the current trend of manufacturing thinner / smaller portable terminals or wearable devices, the space in which electronic modules are installed ("usable device space") is gradually decreasing. In addition, as display devices become highly functional and are ...
