Embodiment

Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skills obtain under the prerequisite of not making creative work belongs to the scope that the utility model is protected.

The mobile terminal antenna that the utility model embodiment provides comprises two first slits that are opened on the metal surface, is provided with waveguide transmission line between the edge of described first slit and described metal surface, and described waveguide transmission line connects described first slit; Described first slit is away from described metal surface lateral edges.

Can know that from above-mentioned because first slit is away from the metal surface lateral edges, so the user can not touch this antenna easily when holding portable terminal, thereby reduces the influence to this antenna performance.

Not only comprise in the portable terminal for receiving and emission GPS (Global Positioning System, global positioning system), Wi-Fi (Wireless Fidelity, Wireless Fidelity), bluetooth, a plurality of antennas (can be referred to as main antenna) of frequency band signals such as honeycomb speech path network, also comprise for the diversity antenna that improves main antenna transmitting-receiving efficient, wherein, Fig. 2 is the layout schematic diagram of portable terminal internal antenna, as shown in Figure 2,3 upsides and downside are respectively the zone that main antenna is arranged in the metal surface, and one side (right side as shown) is the layout area of diversity antenna.For convenience of explanation and understand, following examples are that example describes with the diversity antenna, but are understandable that the utility model can also be applied in the main antenna according to actual conditions.

A schematic diagram of the diversity antenna that Fig. 3 provides for the utility model embodiment.As shown in Figures 2 and 3, this mobile terminal antenna comprises two first slits 1 that are opened on the metal surface 3, is provided with waveguide transmission line 2 between the lateral edges of described first slit 1 and described metal surface, and described waveguide transmission line 2 connects described first slit 1; Because described first slit 1 is away from described metal surface 3 lateral edges, so the user can not touch diversity antenna easily when holding portable terminal, thereby reduces the diversity antenna Effect on Performance.

Here can adjust the signal frequency of antenna receiving-sending by the size (length and/or width) of adjusting first slit.

The form of the above-mentioned main antenna of mentioning is mainly IFA (IFA Inverted-F Antenna, inverse-F antenna), PIFA (PIFA Planar Inverted-F Antenna, planar inverted-F antenna), or Monopole (Monopole, monopole antenna), these forms are the antenna structure of unbalanced, and when diversity antenna is the antenna structure of unbalanced too, because main antenna and classification antenna are to produce coupling by total ground plane, can make the stronger correlation of generation between main antenna and the diversity antenna like this, influence the radiance of antenna, and then cause the performance of MIMO to descend.

In order to reduce the correlation of main antenna and diversity antenna in the high portable terminal, the metal surface 3 among the utility model embodiment is provided with first slit 1 of Fig. 2 or two symmetries shown in Figure 3, so that diversity antenna forms the slot antenna of balanced type.

Need to prove, suitable adjusting can be carried out with the distance of metal surface 3 lateral edges in first slit 1, just make between first slit 1 and metal surface 3 lateral edges by the length (as increasing the length of transmission line) of adjusting waveguide transmission line 2 and have suitable distance, further reduce the influence of holding antenna performance, can guarantee that also antenna can use normally.

As shown in Figure 3, above-mentioned waveguide transmission line 2 comprises:

Two second slits 20, described two second slits 20 are formed on the metal covering between 3 edges, described metal surface and described first slit 1, and each described second slit 20 is corresponding respectively is connected with described first slit 1;

Current feed department 21, described current feed department 21 is formed by the metal covering that is clipped between described two second slits 20, and described current feed department 21 connects radio circuit;

Grounding parts 22, described grounding parts 22 is formed by the metal covering that is positioned at 20 both sides, described two second slits, and described grounding parts 22 connects earthed circuit.

Be not difficult to find out that waveguide transmission line 2 and first slit 1 all are to be formed on the same metal surface by hollow out, namely both realize by a metal surface, can simplify making and the assembling of diversity antenna like this, enhance productivity.

In addition, when the structure of first slit 1 and waveguide transmission line 2 changes, only need change in the metal surface, can the performance of antenna not impacted, also can not need extra structure member to change, reduce the complexity of design alteration.

As shown in Figure 4, described first slit 1 can also favour the edge of described metal surface 3, be equivalent to adjust by the rotation diversity antenna polarised direction of diversity antenna like this, can optimize the antenna pattern of diversity antenna, can also adjust simultaneously and main antenna between the directional diagram coupling, with the correlation between further reduction diversity antenna and main antenna.

The utility model embodiment also provides a kind of portable terminal, comprise metal surface 3, antenna, described antenna comprises two first slits 1 that are opened in metal surface 3, metal covering between the edge of described first slit 1 and described metal surface is provided with waveguide transmission line 2, and described waveguide transmission line 2 connects described first slit 1; Because described first slit 1 is away from described metal surface 3 lateral edges, so the user can not touch antenna easily when holding portable terminal, thereby reduces the influence to antenna performance.

Because this antenna can be previously described any form, therefore here no longer to being repeated in this description.

In addition, because the metal surface can be all-metal construction, so just can improve the texture of portable terminal, and promote the outward appearance of portable terminal.Certainly, can not all-metal also, or be gold-plated surface.

With reference to Fig. 5, comprise two described antennas that are located on the described metal surface 3, two antennas lay respectively at the both sides of metal surface 3, and portable terminal can be realized the MIMO technology by two diversity antennas like this, so that antenna possesses the characteristics of good radiance and low correlation.

Refer again to Fig. 5, in order further to make antenna possess the characteristics of good radiance and low correlation, can make two diversity antenna quadrature arrangement, particularly, first slit 1 of one of them described antenna is perpendicular to first slit 1 of another described antenna.Need to prove, because two diversity antennas have orthogonal property, therefore can in portable terminal, realize many antenna frames in the narrow space comparatively easily.

But above-mentioned two diversity antennas are quadrature arrangement also only is preferred embodiment, and be not limited to this, can also be further by adjusting position and the direction of two diversity antennas, to optimize the coupling between itself and the main antenna, thereby can in movement, realize the MIMO antenna frame greater than double antenna in the terminal, the performance of raising antenna and low correlation etc.

Above-mentioned portable terminal can be mobile phone, panel computer, PDA (Personal Digital Assistant, personal digital assistant), POS (Point of Sales, point-of-sale terminal), vehicle-mounted computer etc.

The above; it only is embodiment of the present utility model; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; can expect easily changing or replacing, all should be encompassed within the protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range of described claim.
