Technical field
The present invention relates to the Antenna Design field of mobile terminal, especially relate to a kind of based on metal edge frame, particularly based on the double-feed antenna of mobile phone metal edge frame.
Background technology
At present, mobile intelligent terminal product, as mobile phone, pad, notebook etc., more and more pursues metal-like, often adopts the structure such as metal edge frame, metal back cover, so just forms challenge to Antenna Design.Also become a large attraction of smart mobile phone because mobile phone is slim simultaneously, the spatial accommodation of antenna is also more and more less, environment around antenna becomes increasingly complex, and along with LTE (Long Term Evolution, Long Term Evolution) development of technology, a mobile phone often needs to put multiple antenna.Under limited space and complex environment, need to make full use of the metal structure of mobile phone own, realize wideband, multiple antennas form, propose unprecedented challenge to the design of antenna.
Existing metal edge frame design major part is using the part of metal edge frame as aerial radiation, the antenna type adopted comprises PIFA (Planar Inverted F-shaped Antenna, planar inverted F-antenna), IFA (Inverted F-shaped Antenna, inverted-F antenna), Loop (coil antenna), Slot (fluting or gap) antenna etc., the corresponding antenna of a usual distributing point.And at present smart mobile phone often antenna space is limited, same mobile phone often comprises 2,3, even 4 antennas, and simultaneously in order to ensure isolation, maintain a certain distance again between antenna, therefore the design space of antenna has too many difficulties to cope with.
Summary of the invention
The object of the invention is to the defect overcoming prior art, a kind of double-feed antenna based on metal edge frame is provided, two kinds of antennas are set in mobile terminal, to make full use of the space in mobile terminal.
For achieving the above object, the present invention proposes following technical scheme: a kind of double-feed antenna based on metal edge frame, comprise metal edge frame, the first antenna excitation and the second antenna excitation, described metal edge frame is provided with for the ground plate by its ground connection, described metal edge frame is isolated into the first frame and second frame two parts by described ground plate, described first antenna excitation and the second antenna excitation lay respectively in described first frame and the second frame, and described first antenna excitation is coupled with the first frame, form aerial radiation loop, form the first antenna; Described second antenna excitation is coupled with the second frame, forms aerial radiation loop, forms the second antenna.
Preferably, the match circuit loading on described first antenna excitation and the second antenna excitation is also comprised.
Preferably, described match circuit is L-type match circuit.

Embodiment
Below in conjunction with accompanying drawing of the present invention, clear, complete description is carried out to the technical scheme of the embodiment of the present invention.
Disclosed a kind of double-feed antenna based on metal edge frame, for intelligent mobile terminal, particularly on mobile phone.As shown in Figure 1, double-feed antenna of the present invention comprises metal edge frame 10, first antenna excitation 20 and the second antenna excitation 30, metal edge frame 10 is connected with the mainboard 41 of terminal body 40, particularly, metal edge frame 10 is provided with the earthing position 11 for it being connected with the mainboard 41 of terminal body, and metal edge frame 10 is connected with the mainboard 41 of terminal body by a ground plate 50, the earthing position 11 of ground plate 50 1 termination metal edge frame, the other end is connected with the mainboard 41 of terminal body, thus by metal edge frame 10 ground connection.
Metal edge frame 10 is divided into first frame 12 and first frame 13 two parts by ground plate 50, and respectively form a spatial accommodation 14,15 between the frame 12,13 on ground plate 50 and both sides, in each spatial accommodation 14/15, a kind of antenna excitation 20/30 is respectively set, namely the first antenna excitation 20 is positioned at spatial accommodation 14, second antenna excitation 30 that the first frame 12 and ground plate 50 formed and is positioned at the spatial accommodation 15 that the second frame 13 formed with ground plate 50.
First antenna excitation 20 and the second antenna excitation 30 use respective radiation fin to encourage respectively, and the first antenna excitation 20 is coupled with the first frame 12, form aerial radiation loop, form the first antenna; Second antenna excitation 20 is coupled with the second frame 13, forms aerial radiation loop, forms the second antenna.First frame 12 and the second frame 13 are one, and namely two kinds of antenna excitations share a metal edge frame.In the embodiment of the present invention, first, second antenna excitation 20,30 is respectively LTE and gps antenna excitation, certainly, is not limited to these two kinds.
