Embodiment Construction

[0047] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0048] Refer to Figure 1 to Figure 4 An antenna element 10 according to one embodiment of the present invention will be described. FIG. 1 is a diagram showing a model in which an antenna element 10 is mounted on a liquid crystal unit of a notebook personal computer. figure 2 is a perspective view of the antenna element 10 . image 3 is a front view of the antenna element 10 . Figure 4 is a right side view of the antenna element 10 . In Figure 1 to Figure 4 Here, the X-axis direction represents the left-right direction (width direction, horizontal direction), the Y-axis direction represents the front-rear direction (depth direction, thickness direction), and the Z-axis direction represents the vertical direction (height direction, vertical direction).

[0049] As shown in FIG. 1 , the antenna element 10 is arranged at the center of the upper edge of the...

Abstract

An antenna element is disclosed. A conductive plate is adapted to be electrically connected to an electric ground, and has a first edge. A second edge opposes the first edge and is formed with a first slit elongated in a first direction. A third edge intersects the first edge. A recessed part intersects the first edge and the third edge. A conductive member elongates from the second edge in the first direction.

Description

technical field [0001] The present invention relates to an antenna element, and more particularly to a broadband antenna element mounted on a module or the like connected to a main body of a portable electronic device or an extension terminal (selection terminal) of the portable electronic device. Background technique [0002] The UWB (Ultra Wide band) technology, as its name implies, means ultra-wideband wireless, and is defined as a wireless technology with a bandwidth of 25% or more of a center frequency or 1.5 GHz or more. In a word, UWB technology is a technology that uses ultra-wideband short pulses (usually below 1ns) to communicate and cause a revolution in wireless. [0003] The decisive difference between existing wireless technology and UWB technology can be said to be whether there is a carrier or not. In existing wireless technologies, a sine wave of a certain frequency called a carrier is modulated by various methods to transmit and receive data. In contrast,...
