Alternatively, the second resistance 20321 may be a zero ohm resistance. The zero ohm resistance is not truly zero, and is actually a very small resistance. The switching unit is in a grounded state, i.e. the section is in a non-operating state.
In one embodiment of the present application, the principle of operation of the antenna module 200 is as follows.
When the user is in a non-game state, i.e., when the electronic device 100 is in a non-landscape state, the user is mainly considered to be holding to browse pages or holding to talk, i.e., in a head-hand mode.
At this time, the second switching unit 2032 is in a short-circuit state, or in a small-inductance or large-capacitance mode, and the second grounding point 2033 and the second break 2031 are substantially in a short-circuit state, and the second section 203 does not participate in radio frequency and is in a non-operation state.
In the embodiment of the present application, the inductance is taken as an example, as shown in fig. 2, the first switch 20222 can switch the frequency band of the antenna from the first frequency band to at least two frequency bands such as the nth frequency band, and at this time, the frequency band modes corresponding to the antenna are mainly distributed between the first grounding point 2023 and the second grounding point 2033. Because the structures between the first grounding point 2023 and the second grounding point 2033 are all outside the hands of the user, and have a certain space with the hands, the handheld mode and the head-hand mode have better performance.
When the user is in a game state, i.e., when the electronic device 100 is in a landscape state, the main consideration is a user landscape game mode or a landscape video mode, i.e., optimizing the gamer performance.
At this time, the first switch 20222 unit 2022 is in a short-circuit state, or in a small-inductance or large-capacitance mode, the first grounding point 2023 is substantially in a short-circuit state with the first break 2021, and the first section 202 does not participate in radio frequency, and is in a non-working state.
In the embodiment of the present application, the second switching unit 2032 switches the frequency band of the antenna from the first frequency band to at least two frequency bands such as the nth frequency band by taking the inductance as an example, as shown in fig. 3, and at this time, the frequency band mode corresponding to the antenna is mainly distributed between the second break 2031 and the feeding point 201. Since the structure between the second break 2031 and the feeding point 201 is not substantially grasped by the hand, the performance of the game hand mode is good.
In one possible embodiment of the present application, the electronic device 100 may include a charging interface 300, where the charging interface 300 is located on a first side of the electronic device 100, and the first break 2021 and the second break 2031 are located on one side of the charging interface 300.

So that when the user uses the electronic device 100 in a certain state, one break is not blocked, and the electronic device can work normally.
As shown in fig. 5, alternatively, the second section 203 may have an inverted F-shaped structure, the first break 2021 may be located on a first side, and the second break 2031 may be located on a second side of the electronic apparatus 100, where the first side is perpendicular to the second side.
That is, when the antenna module 200 is in the vicinity of the bottom charging port of the electronic device 100, the first section 202 is on a first side, i.e., bottom side, and the second section 203 is to the F-shaped antenna, a portion of which is on the bottom side and a portion of which is on a second side, i.e., side, to form an inverted F-shape. As shown in fig. 1, in the game hand mode, the second break 2031 of the second section 203 is located at a side edge and is not easy to be blocked, so that the antenna performance is better and the signal is more stable. In the hand-held mode or the head-hand mode of the non-transverse screen, the first break 2021 of the first section 202 is at the bottom edge and is not easy to be blocked, so that the antenna performance is better at the moment, and the signal is more stable.
Alternatively, the second break 2031 may be located on a third side of the electronic apparatus 100, with the first side perpendicular to the third side.
That is, the second section 203 may be located on the second side or on the third side, wherein both the second side and the third side are perpendicular to the first side.
In one possible embodiment of the application, as shown in fig. 6, the antenna module 200 is located on a second side or a third side, both of which are perpendicular to the first side.
That is, the antenna module 200 may be located at any side of the electronic device 100, where the antenna module 200 is linear and distributed from top to bottom. As shown in fig. 4, in the game hand mode, the second break 2031 of the second section 203 is located at the lower half of the side edge, so that the second break 2031 is not easily blocked, and the antenna performance is better and the signal is more stable. In the hand-held mode or the head-hand mode of the non-transverse screen, the first break 2021 of the first section 202 is located at the upper half part of the side edge, so that the antenna is not easy to be shielded, the antenna performance is good, and the signal is stable.
As shown in fig. 7, in one possible embodiment of the present application, at least one antenna module 200 includes a first antenna sub-module 210 and a second antenna sub-module 220; the first antenna sub-module 210 is located on a second side of the electronic device 100, and the second antenna sub-module 220 is located on a third side of the electronic device 100; the second side and the third side are perpendicular to the first side.
That is, the number of the antenna modules 200 may be two, and the two antenna modules 200 are respectively located at two sides of the electronic device 100, so that signals in any mode can be enhanced, and user experience is further improved.
