Problems solved by technology
Depend on Figure 1B It can be seen from the figure that the antenna 90 can only transmit in the frequency range of 2.5GHz and 5GHz, and the matching of the antenna 90 at the low frequency of 2.5GHz is not ideal.
Therefore, the frequency band that the antenna 90 in the prior art can transmit is very limited.

The invention discloses a thin antenna which is used in an electronic device for transmitting radio signals. The thin antenna comprises a base plate, a first radiation area, a first grounding zone and a feed surface; wherein, the base plate comprises a first plane and a second plane; the first radiation area is printed on the second plane; the first grounding area is printed on the first plane; the feed surface is printed on the first plane and is provided with feed points; the area of the feed surface is smaller than that of the first radiation area, and the position of the feed surface is partially included in the area of the first plane corresponding to the first radiation area. The thin antenna also comprises a second grounding area which is printed on the second plane and is conducted with the first grounding area. The thin antenna also comprises a short circuit component which is printed on the second plane and connects the first radiation area and the second grounding area.
Description
technical field [0001] The invention relates to a thin antenna and an electronic device with the thin antenna, in particular to a coupled feed thin antenna and an electronic device with the thin antenna. Background technique [0002] With the advancement of technology, electronic products on the market have become increasingly thinner and smaller. Especially for notebook computers, users not only require the functions of the notebook computer, but also require the notebook computer to have a thinner and lighter volume. Under this circumstance, the institutional space of the notebook computer is bound to be reduced. As a result, there is no way for traditional antennas to fit into the institutional space of a laptop. [0003] A thin antenna that can be placed in the mechanism space of a notebook computer has been disclosed in the prior art. Please refer to the following Figure 1A There is a schematic diagram of a thin antenna disclosed in the prior art. The prior art ant...
