Embodiment Construction

[0026] Please refer to FIG. 2 and FIG. 3 at the same time. FIG. 2 is a perspective view of the antenna device 20 according to an embodiment of the present invention, and FIG. 3 is a side view of the antenna device 20 corresponding to FIG. 2 . The antenna device 20 includes a first planar metal sheet 200 , a second planar metal sheet 210 and a third planar metal sheet 220 . The length of the first planar metal sheet 200 is L1 and the width is W1. The second planar metal sheet 210 has a length L2 and a width W2, and has a first side S1 and a corresponding second side S2. The first side S1 is coupled to the first planar metal sheet 200 , and the second side S2 is coupled to the third planar metal sheet 220 . The length of the third planar metal sheet 220 is L3, the width is W3, and L3 is smaller than L1. In addition, it can be seen from FIG. 1 that the third planar metal sheet 220 and the first planar metal sheet 200 are substantially parallel to each other and overlap with at ...

Abstract

The invention provides an antenna device with low production cost and suitable for various kinds of wireless communication systems. The antenna device comprises a first planar metal sheet, a second planar metal sheet and a third planar metal sheet, wherein the first planar metal sheet has a first length; the second planar metal sheet has a first edge and a second edge corresponding to but not connected with each other, and the first edge is coupled with the first planar metal sheet; the third planar metal sheet has a second length and is coupled with the second edge; the second length is smaller than the first length; and the third planar metal sheet and the first planar metal sheet extend in the same direction, that is to say, the third planar metal sheet is parallel to and is superposedwith the first planar metal sheet. The antenna device has the advantages of simple process and low cost.

Description

technical field [0001] The invention relates to an antenna device and its related electronic device, in particular to a three-dimensional multi-frequency antenna device and its related electronic device. Background technique [0002] Antennas are used in wireless communication products to transmit or receive radio waves to transmit or exchange radio signals. Generally, electronic products with communication functions, such as mobile communication devices, usually access the network through built-in or exposed antennas to perform communication functions. With the development of wireless communication technology, the operating frequencies of different wireless communication systems may be different. For example, the Global System for Mobile Communications (GSM) 850, 900, 1800 and 1900 wireless communication systems use center frequencies around 850, 900, 1800 and 1900 hertz respectively. Therefore, in order to allow users to access different wireless communication systems mo...
