Abstract
The utility model provides a flexible circuit board antenna, used in portable mobile equipment, such as mobile phones, personal digital assistants (PDA), notebook computers and the like. The flexible circuit board antenna comprises an adhesion layer, a carrier layer arranged on the adhesion layer, a metal radiating body arranged on the carrier layer, and a surface covering layer covered on the metal radiating body, wherein aluminum foil patterns are used as the metal radiating body, and a passive film is used as the surface covering layer. Compared with FPC (Flexible Printed Circuit) antennas used in other mobile phones, PDAs and notebook computers, the flexible circuit board antenna disclosed by the utility model has the advantages that the production of the passive film of the antenna is much simpler than that of solder resist ink and a metal plating layer, and more cost can be saved.
Description
Technical field
The utility model relates to the wireless telecommunications antenna, especially relates to the flexible PCB antenna.
Background technology
Antenna is widely used in numerous portable mobile apparatus, for example mobile phone, personal digital aid (PDA) (Personal Digital Assistant, PDA), in the notebook computer, be used for transmitting and receiving signal.For the requirement on attractive in appearance, antenna more and more is built in device interior at present, forms so-called built-in aerial.In built-in aerial, with flexible PCB (Flexible Printed Circuit, FPC) because of its can free bend, coiling, folding, can require to arrange arbitrarily according to space layout, the advantages such as volume and weight that can dwindle electronic product are subjected to the favor of manufacturer.
The FPC antenna is attached to the mobile phone shell inboard after using the FPC material to make, and links with support and miscellaneous part.
FPC antenna primary structure such as Fig. 1 of being used for mobile phone, PDA, notebook computer at present show.At bottom the adhesion layer 10 of for example double faced adhesive tape that attaches usefulness being arranged, is one deck carrier 11 on it, for example flexible plastic film (being typically the PET film).Be metal radiant body 12 then, it is the figure that is made of Copper Foil.Uppermost is surface coating 13, and it is the welding resistance printing ink or the coat of metal etc.In addition, surface coating 13 is cover part metal radiant body just, but needs an extra gold plate 14 to cover another part.
In above-mentioned FPC antenna cost structure, the surface coating 13 of covering metal radiant body and the accounting of gold plate 14 are higher.Therefore, the expectation antenna is guaranteeing to reduce this part cost under the radio-frequency performance.
The utility model content
Problem to be solved in the utility model is to propose a kind of FPC antenna that reduces cost.
The technical scheme that the utility model adopted is to propose a kind of flexible PCB antenna, and it comprises adhesion layer, is located at the carrier layer on the adhesion layer, the surface coating that is located at the metal radiant body on the carrier layer and covers the metal radiant body.Wherein, the metal radiant body is the aluminium foil pattern, and surface coating is a passivating film.
In above-mentioned flexible PCB antenna, this adhesion layer is a double faced adhesive tape.
In above-mentioned flexible PCB antenna, this carrier layer is a flexible plastic film.
In above-mentioned flexible PCB antenna, this passivating film is this aluminium foil to be carried out Passivation Treatment obtain.
Compare with the FPC antenna of present other mobile phones, PDA, notebook, the passivating film of antenna of the present utility model is made resistivity solder paste China ink, the coat of metal and is made simplyr, more saves cost.
Description of drawings
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent, below in conjunction with accompanying drawing embodiment of the present utility model is elaborated, wherein:
Fig. 1 illustrates the FPC antenna structure of prior art.
Fig. 2 illustrates the FPC antenna structure of the utility model one embodiment.
Embodiment
The flexible PCB that embodiment of the present utility model will describe (Flexible Printed Circuit, FPC) antenna, can be used for mobile phone, personal digital aid (PDA) (Personal Digital Assistant, PDA), notebook computer, panel computer or other use the portable terminal of radio communications.
Fig. 2 illustrates the FPC antenna structure of the utility model one embodiment.Described with reference to Fig. 2, the bottom of antenna is the adhesion layer 20 such as double faced adhesive tape, is one deck carrier 21 on it.Carrier layer 21 is selected flexible plastic film, for example PET (polyethylene terephthalate) film usually.On carrier layer 21 main part of antenna, metal radiant body 22.In the utility model, aluminium is as the material of metal radiant body.On carrier layer, form the aluminium foil pattern by methods such as plating.Metallic aluminium has fine conductivity, and is approaching with metallic copper, and the same a FPC antenna of making respectively with aluminium and copper has essentially identical radio-frequency performance.
Holding above-mentionedly, is surface coating 23 on the metal radiant body 22, and this surface coating 23 is one deck passivation films, covers all surfaces of metal radiant body 22.This passivating film has good conductivity, and salt fog resistance.Can directly substitute the welding resistance printing ink or the coat of metal of prior art under certain condition.For example, present quantity accounting higher be hidden in antenna in the casing, can use the antenna structure of the surface coverage passivating film that the utility model embodiment proposed.
In one embodiment, form the technology of passivating film, for example be to use chemical medicinal liquid to soak Tunization processing aluminium foil surface.
Compare with the FPC antenna of present other mobile phones, PDA, notebook, the production procedure of antenna of the present utility model is easier, and production capacity is higher, the production material and facility environmental protection more that relates to, and cost is lower.
Though the utility model discloses as above with preferred embodiment; right its is not in order to limit the utility model; any those skilled in the art; in not breaking away from spirit and scope of the present utility model; when doing a little modification and perfect, therefore protection range of the present utility model is worked as with being as the criterion that claims were defined.
