Antenna system for wireless communication device
First Claim
1. An antenna system for a wireless communication device, comprising:
- a first metal slice, substantially conforming to a rectangular shape, formed with a first slot structure substantially extending along a horizontal direction;
a second metal slice, disposed on a side of the first metal slice along the horizontal direction, substantially conforming to a rectangular shape, formed with a second slot structure substantially extending along the horizontal direction, and partially connected to the first metal slice;
a first signal transmission line, comprising;
a first metal wire, electrically connecting to a first feeding terminal of the first metal slice, for transmitting signals, wherein the first feeding terminal is substantially disposed on a side of the first slot structure along a vertical direction;
a first isolation layer, covering the first metal wire; and
a first metal weave, covering the first isolation layer and electrically connecting to a first signal grounding terminal to connect to a first signal ground, wherein the first signal grounding terminal is substantially disposed on another side of the first slot structure along the vertical direction; and
a second signal transmission line, comprising;
a second metal wire, electrically connecting to a second feeding terminal of the second metal slice, for transmitting signals, wherein the second feeding terminal is substantially disposed on a side of the second slot structure along the vertical direction;
a second isolation layer, covering the second metal wire; and
a second metal weave, covering the second isolation layer and electrically connecting to a second signal grounding terminal to connect to a second signal ground, wherein the second signal grounding terminal is substantially disposed on another side of the second slot structure along the vertical direction;
wherein an adjacent portion of the first metal slice and the second metal slice is further formed with a third slot structure;
wherein the third slot structure is a closed slot with a length substantially equal to a quarter of a wavelength of wireless signals corresponding to a wireless frequency band of the wireless communication device, or the third slot structure is an open slot with a length substantially equal to a half of a wavelength of wireless signals corresponding to a wireless frequency band of the wireless communication device.

Abstract
The present invention discloses an antenna system for a wireless communication device, which includes a first metal slice formed with a first slot structure, a second metal slice formed with a second slot structure, a first signal transmission line, and a second signal transmission line, wherein when the first metal slice and the second metal slice are not connected and have a distance between each other, a feeding direction of the first transmission corresponding to the first metal slice is substantially opposite to a feeding direction of the second transmission corresponding to the second metal slice; or when the first metal slice and the second metal slice are partially connected, a feeding direction of the first transmission corresponding to the first metal slice is substantially the same as or different to a feeding direction of the second transmission corresponding to the second metal slice.
