Embodiment Construction
[0031] As mentioned in the background technology section, the full metal casing antenna device in the prior art uses a PIFA antenna. Since the PIFA antenna is very sensitive to the connection position between the feed source and the ground, the mobile communication terminal using this antenna structure has a large impact on the overall length and The width requirements are relatively high, otherwise, it is easy to cause the antenna resonant frequency to be too long or too short. Moreover, the mobile communication terminal using this antenna structure is greatly affected by the user's head-hand, and it is difficult to meet the index of the mobile communication terminal antenna performance in the head-hand test.
[0032] In view of this, an embodiment of the present invention provides an antenna structure, which is applied to a communication terminal, and the communication terminal includes: a metal back shell arranged on the back of the communication terminal and a main board ar...

The embodiment of the invention discloses an antenna structure and a communication terminal. The communication terminal comprises a metal back shell and a motherboard, wherein the metal back shell comprises a first back shell and a second back shell. The antenna structure comprises an excitation source, a first metal wiring, a second metal wiring and a control switch, wherein the excitation source is arranged on the motherboard; the first metal wiring receives antenna signals outputted by the excitation source and transmits the signals to the first back shell; the second metal wiring receives the antenna signals outputted by the first back shell; the control switch is arranged on the motherboard; the control switch is used for controlling transmission of antenna signals between the second metal wiring and the motherboard; and in a plane parallel with the first back shell, a gap exists between the second metal wiring and the motherboard. According to the antenna structure provided by the embodiment of the invention, the structure is simple, resonance frequency is convenient to adjust, the overall length and the width of the communication terminal to which the antenna structure is applied are lowly required, the problem that the antenna resonance frequency is over long or over short can be avoided, and influences from the head and the hand of the user during the communication terminal use process can be reduced.
Description
technical field [0001] The present invention relates to the technical field of antennas, in particular to an antenna structure and a communication terminal including the antenna structure. Background technique [0002] With the continuous improvement of users' requirements for the appearance of mobile communication terminals, more and more mobile communication terminals with metal appearance appear on the market, but the all-metal back covers of most mobile communication terminals have many gaps or plastic areas. To meet its antenna performance requirements. There are only two slits on the metal back cover of a very small number of mobile communication terminals. However, the all-metal shell antenna device described in this patent application uses a PIFA antenna. Since the PIFA antenna is very sensitive to the connection position between the feed source and the ground, the mobile communication terminal using this antenna structure requires the overall length and width. Hig...
