Accompanying drawing explanation

Below in conjunction with accompanying drawing, embodiments of the invention are described in detail.

Fig. 1 is embodiment of the present invention structural representation.

Fig. 2 is the antenna detail view of the present invention.

Fig. 3 is the frequency response chart of the present invention.

Specific embodiments

Embodiment below in conjunction with accompanying drawing describes the present invention in detail.In order to describe the present invention more intuitively, 2, accompanying drawing It is the part intercepting accompanying drawing 1, it is accordingly required in particular to it is noted that the radio-frequency (RF) switch in the accompanying drawing of all antennas is all with an electricity Sense carrys out symbolistic instead of.

As an embodiment, described PCB top and low side have clearance zone, putting for antenna module Put, wherein the left side of 2 main antenna placement PCB, for placement symmetrical above and below;2 high frequencies are placed on the back of the body of PCB Right side of face, is placement symmetrical above and below equally.

As an embodiment, described becket has 6 gaps, wherein in the middle of top and middle each one of low side, the right side Side becket and each 2 gaps of left side becket, these gaps are all that symmetry is cracked and size is identical, and the size in gap is permissible The most effectively adjust.It is same because becket is divided into 6 parts, described becket by these 6 gaps (2) being fully contacted with PCB, becket (5) is connected together with pcb board by 2 lamellules, remaining 4 metals Ring is each connected with an antenna module, forms a part for radiating element.

As an embodiment, antenna module, coupling branch and becket (3) collectively constitute the radiating element of antenna, Wherein antenna module is made up of feed branch and coupling branch again.Feed branch comprises and is made up of an electric capacity, two inductance Match circuit, the first end is provided with distributing point, and the second end is provided with the first earth point, the first described earth point and pcb board The metal ground at the back side is connected.Coupling branch the first limit is formed with feed branch and couples, and end is provided with the second earth point, described It is connected the metal at the second earth point and the pcb board back side;Wrap from the first described limit to described the second earth point (15) Include be sequentially connected with the first limit (12), the second limit, the 3rd limit, the 4th limit, the 5th limit, the 6th limit, the 7th limit, each adjacent limit Orthogonal, the 3rd described limit is orthogonal with becket to be connected together.

As an embodiment, the first limit of coupling branch is not contact with feed branch, has small between the two Gap, thus form couple feed, make bandwidth range be expanded, general distance between both could be arranged to 0.2- 0.5mm, concrete numerical value can be according to actual test result optimum selecting.

As an embodiment, there is a radio-frequency (RF) switch on the 8th limit of coupling paper slip, described radio-frequency (RF) switch is by several The suitably inductance composition of numerical value, one effective inductance value of each on-off control participates in the radiation of antenna, and different inductance value can So that Antenna Operation is in different low-frequency ranges such as LTE700, GSM850 and GSM900 frequency range.Simultaneously at front end it is also ensured that Cover 1.71GHz-2.69GHz, meet the current 4G technology demand for antenna.
