Problems solved by technology
[0002] At present, most of the metal frame or three-section metal antenna feeder is usually placed at the corner of the mobile phone, which is easy to be touched or covered by hands, which will easily cause a large loss of low frequency of the antenna.
If the slot is on the side, it is more likely to cause serious attenuation of low-frequency signals
How to solve the problem of large loss and serious attenuation of low-frequency signals is an urgent problem to be solved

Embodiment Construction
[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0018] Such as figure 1 and figure 2 As shown, the antenna with switchable antenna feed point of the present invention includes an antenna 1, and the antenna 1 is a metal antenna. At least two antenna feed points 2 are arranged on the surface of the antenna 1, and the antenna feed point 2 passes through the antenna. The switch is connected with the radio frequency front end to switch between the two antenna feed points 2 , and at least one ground point 3 is provided on the surface of the antenna 1 .
[0019] The radio frequency front-end includes a transmission path and a reception path, and the radio frequency front-end is the prior art, and will not be described in detail here.
[0020] As a preference of the present invention, the antenna feed point 2 is provided with two, respectively the first antenna feed point 4, the second antenna f...

The present invention discloses a feed point switchable antenna. The feed point switchable antenna comprises an antenna; at least two antenna feed points are arranged on the surface of the antenna; the at least two antenna feed points are connected with a radio frequency front end through an antenna switch; and at least one grounding point is arranged on the surface of the antenna. The present invention also provides a mobile device and a mobile phone. According to the feed point switchable antenna, two antenna feed points which are far away from each other are arranged on the surface of the antenna and are connected with the radio frequency front end through the antenna switch; when the signal strength of one of the antenna feed points is weak, the other antenna feed point can be enabled through switching by means of the antenna switch, and therefore, the strength of low-frequency signals can be ensured, and the loss of the low-frequency signals can be reduced.
Description
technical field [0001] The invention relates to an antenna technology, in particular to an antenna with a switchable feeding point, a mobile terminal and a mobile phone. Background technique [0002] At present, the feed pins of most metal frames or three-segment metal antennas are generally placed at the corners of mobile phones, which are easy to be touched or covered by hands, which will easily cause a lot of low-frequency loss of the antenna. If the slot is on the side, it is more likely to cause serious attenuation of low-frequency signals. How to solve the problem of large loss and serious attenuation of low-frequency signals is an urgent problem to be solved. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides an antenna, a mobile terminal, and a mobile phone with a switchable feed point, so as to ensure that when the low-frequency signal is weak, it can be switched to a feed point with a stronge...
