Description

Antenna and electronic equipment

This application claims priority from a Chinese patent application filed with the Chinese Patent Office on June 08, 2018 with application number 201810584602.4, the entire contents of which are incorporated herein by reference.

Technical field

The present application relates to the field of wireless communication technologies, for example, to an antenna and an electronic device.

Background technique

In the mobile terminal, the introduction of the metal case brings fatal problems such as coupling deterioration and signal shielding to the antenna. The harsh antenna environment seriously affects the antenna performance and greatly increases the difficulty of antenna design for the mobile terminal.

Based on this, for mobile terminals with all-metal casings, the most representative of the antenna design is the design of dividing the metal back plate of the metal casing into three sections. For example, the antenna structure shown in FIG. The gap between the cut edge and the metal back plate is set near the L-type monopole antenna, which can generate a 1575 megahertz (MHz) resonance. The antenna structure shown in Figure 2 is also used. Figure 2 uses a planar inverted F antenna (Planner Inverted Antenna, PIFA), and the F antenna uses left and right branches as a radiation path, which can generate wireless local area networks (Wireless Local Area Networks, WLAN) / Global Positioning System (Global Positioning System, GPS) two resonance points. In the antenna structure shown in FIG. 3, FIG. 3 uses a metal frame and a system ground to connect through a metal shorting sheet, and can generate a low frequency of 824 MHz to 960 MHz and a high frequency of 1710 MHz to 2700 MHz.

Although the above three antenna design schemes successfully solved the fatal interference caused by a good metal conductor to the antenna of a mobile terminal, grounding the metal frame in sections to eliminate the impact of the metal casing on the antenna performance will inevitably destroy the metal casing. Integrity is not suitable for the trend design of all-metal casing, and the antenna designed in this way takes up a large space.

In order to save more space, as shown in the antenna structure shown in FIG. 4, FIG. 4 electrically connects the magnetically permeable sheet 111 of the speaker 11 and the circuit board 13 in the mobile terminal to make the antenna 100 of the mobile terminal. For a mobile terminal with a metal case, the radiant energy of the antenna will be reflected and absorbed by the metal case, which will cause a serious degradation of the antenna performance.

Therefore, without destroying the integrity of the metal casing, how to design an antenna capable of ensuring good radiation performance has become a problem that needs to be solved at present.

Detailed ways

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. With this, the application process of how to apply technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

Here, it should be noted that, in practical applications, the shape of the metal backplane 1101 is generally rectangular, for example, a smartphone, an iPad, or a mobile broadband (Mobile Boradband (MBB)) communication device. Therefore, the metal backplane surrounds the metal backplane. The at least one metal frame 1101 may include two oppositely disposed short frames and two oppositely disposed long frames. In an embodiment, a gap of a certain length is set between the two short frames and the edge of the metal back plate, and the gap can be filled with a non-metal material by using a nano injection molding technology. The shape of the slot may be U-shaped, L-shaped, or "one", and the size of the slot may be determined according to actual frequency band requirements and debugging.

The antenna component 120 includes a first radiator 1201 and a second radiator 1202; one end of the first radiator 1201 is connected to the ground and is coupled to the second radiator 1202; the second radiator 1202 It is connected to the first radiator 1201 through the feeding point 130 and is coupled to the metal frame 1102.

Here, it should be noted that, in other embodiments, the setting range of the distance between the first radiator 1201 and the second radiator 1202 is [0.5mm, 4mm], and the second radiator 1202 The setting range of the distance from the metal frame 1102 is (0mm, 3mm), so that the first radiator 1201 and the second radiator 1202 and the second radiator can be guaranteed. A better coupling effect is obtained between 1202 and the metal frame 1102, so that the antenna 100 has better radiation efficiency. The first radiator 1201 is a ground parasitic patch, and the second radiator 1202 is a monopole. Understandably, in order to achieve the multi-frequency characteristics of the antenna without increasing the size of the antenna as much as possible, one or more ground parasitics can be added above or around the microstrip patch (such as a monopole patch). SMD and use coupling technology to excite new resonance points. Monopole patches have the characteristics of high radiation efficiency, wide bandwidth and small size. Compared with PIFA antennas, monopole patches are very suitable for antenna design of ultra-thin terminals.

Here, it should be noted that at least a part of the projection of the second radiator 1202 in the vertical direction of the metal back plate 1101 falls within the gap, so that the second radiator 1202 and the metal frame 1102 Only a good coupling effect can be obtained between them, so that the antenna 100 can obtain better radiation efficiency.

In other embodiments, the projections of the first radiator 1201 and the second radiator 1202 in the vertical direction of the metal back plate 1101 each fall within the gap.

Here, the projections of the first radiator 1201 and the second radiator 1202 in the vertical direction of the metal back plate 1101 both fall within the gap, and the radiation efficiency obtained by the antenna 100 is only as described above. The radiation efficiency obtained by the projection of the second radiator 1202 in the vertical direction of the metal back plate 1101 by at least a portion falling within the gap is better.

In other embodiments, the length of the first radiator 1201 is at least 0.5 times the length of the second radiator 1202.

Features. For example, if the metal device 140 is a loudspeaker, the sound cavity of the loudspeaker can be used as the bracket of the antenna component 120, and the wiring of the antenna component 120 and the connection of the feeding point 130 can be performed on the bracket, which can greatly save The space occupied by the antenna in the mobile terminal. According to the current technology level, the antenna component 120 can be implemented by a Flexible Printed Circuit Board (FPCB), which is not only cheap, but also very suitable for the antenna pattern of the planar structure, which is convenient for non-metals attached to the metal device 140. Portion 1402 (for example, a sound cavity of a speaker).

Based on the same technical concept as above, as an example of the antenna 100, as shown in FIG. 8, FIG. 8 shows a diversity antenna 200 capable of covering a long-term evolution (LTE) B41 frequency band, as shown in FIG. The antenna 200 includes: an all-metal casing 1 (equivalent to the all-metal casing 110), a metal device 2 (equivalent to the metal device 140), and a monopole patch 3 (as the second radiator 1202). Example), parasitic branches 4 (as an example of the first radiator 1201), a feed point 5 (equivalent to the feed point 130), a ground plate 6 (for grounding), and an inductance element 7 (as the Example of electronic component 150). among them,

Understandably, here, using the non-metal part 22 of the metal device 2 as a bracket for the antenna component, the unipolar patch 3 and the parasitic branches 4 can be routed on the bracket and the feeding point 5 can be performed on the bracket. Connection, thereby greatly saving the physical space occupied by the antenna in the mobile terminal. The shape of the metal portion 21 of the metal device 2 is not limited herein, and the shape of the metal portion 21 may be a rectangular parallelepiped, a cube, or a cylinder, which can greatly expand the application range of the antenna.

The size of the monopole patch 3 and the parasitic branch 4 mainly determines the resonance frequency of the antenna 200.

In order to reduce the influence of the metal part 21 of the metal device 2 on the antenna performance, in practical engineering applications, the distance d between the metal part 21 of the metal device 2 and the parasitic branch 4 should be greater than 1.5 mm, so The effect on the performance of the antenna 200 is minimal. In addition, as shown in FIG. 10, in the embodiment of the present application, the setting range of the length L1 of the unipolar patch 3 is [10mm, 13mm], and the setting range of the horizontal length L2 of the parasitic branch 4 is [9mm, 11mm].
