Abstract

The invention relates to a multifrequency antenna and an electronic device with same. Specifically the invention is the multifrequency antenna used in the electronic device and for transmitting wireless signal. The multifrequency antenna comprises a substrate, a radiation component, a grounding component, a short-circuit component and a load point, wherein the radiation component, grounding component and short-circuit component are arranged on the substrate; the short-circuit component comprises a first end and a second end, the first end is connected with the radiation component and the second end is connected with the grounding component, wherein a first slot hole is arranged between the radiation component and the short-circuit component. The load point is used to feed electrical signals, wherein the load point is actually arranged between the side of the substrate and the short-circuit component. The invention can realize the effect of broadband transmission.

Description

technical field [0001] The invention relates to a multi-frequency antenna, in particular to a multi-frequency antenna which can utilize the adjustment slot to achieve broadband transmission. Background technique [0002] With the advancement of science and technology, the transmission of electronic products on the market using wireless communication systems has become more and more popular. For multimedia data that requires a large amount of data, a transmission antenna with a larger bandwidth is more needed. As a result, traditional antennas cannot meet the requirements. [0003] One type of antenna has been disclosed in the prior art. Please refer to the following Figure 1A There are schematic diagrams of antennas related to the prior art. A prior art antenna 90 is disclosed in US Patent Publication No. 6,812,892B2. The prior art antenna 90 has a radiation element 91 , a connection element 92 , a ground element 93 and a feed point F. As shown in FIG. The connection e...
