The radiation efficiency of strong antenna structure 130.Antenna structure 130 above-mentioned also can be as replaced the antenna structure 430 of Fig. 4, without shadow
Ring technical effect of the invention.In further embodiments, mobile device 500 can also have multiple recessed areas 570, to accommodate
Multiple separable antenna elements 580, so as to formed a multiple-input and multiple-output (Multi-Input and Multi-Output,
MIMO) antenna system.Remaining feature of the mobile device 500 of Fig. 5 A, 5B, 5C is all similar with the mobile device 100 of Figure 1A, 1B,
So similar operating effect can be achieved in two embodiments.
The present invention proposes a kind of novel mobile device comprising concealed antenna structure.Such antenna structure can be with
Metal back cover (A part) or display frames (B part) are mutually integrated, and effectively utilize mobile device appearance marginal portion and its
The space of adjacent.Approximately, the present invention at least has the advantages such as small size, broadband, and beautification mobile device appearance,
Therefore it is well suited in the action communication device applied to various narrow frames (Narrow Border).
It is worth noting that, it is limit of the invention that above-described component size, component shape and frequency range are all non-
Condition processed.Antenna designers can need to adjust these setting values according to different.Mobile device and antenna structure of the invention is simultaneously
It is not limited only to the illustrated state of Fig. 1-5.The present invention can only including Fig. 1-5 one or more any embodiments any one or
Multinomial feature.In other words, and the feature of not all diagram must be implemented on mobile device and antenna structure of the invention simultaneously and work as
In.
Ordinal number in this specification and claim, such as " first ", " second ", " third " etc., each other
There is no precedence relationships sequentially, are only used for mark and distinguish two different elements with same name.
Though the present invention is disclosed as above with preferred embodiment, the range that however, it is not to limit the invention, any this field
Technical staff, without departing from the spirit and scope of the present invention, when a little variation and retouching, therefore protection of the invention can be done
Range is subject to view the attached claims institute defender.
