Abstract
The invention relates to a multi-curve antenna which comprises a radiation conductor and a bearing piece, wherein an outer annular part in an arc curve shape is formed at the outer side edge of the radiation conductor, and a fragment of the arc curve is provided with a notch; a radiation conductor conducting path is patterned in a central part at the inner side of the radiation conductor; and the bearing piece is used for bearing the radiation conductor. The manufacturing method of the multi-curve antenna comprises the following steps of: firstly, arranging a metal sheet with a flat surface; then bending the metal sheet through a gravity pressurizing and shaping procedure to form the radiation conductor form with the arc curve on the outer annular part; patterning the central part of the radiation conductor into the conductor path designed in advance, and punching and reserving a connecting section on the outer annular part; and finally, cutting off the connecting section to finish manufacturing the multi-curve antenna.

Conventionally antenna, flat appearance excision die-cut through drawing, radiation conductor patterning by sheet metal, conductor are electroplated and paste after a series of programs such as plastic, just can obtain complete antenna finished product, how effectively to shorten processing procedure, improve workmanship, constantly promote finished product yield simultaneously, become the problem of relevant design person's active research.
[summary of the invention]
The present invention's object is to provide a kind of many curve antennas and manufacture method thereof, through this, provides processing procedure to simplify, and volume production rapidly and the antenna product of quality yield height.
For reaching above-mentioned purpose, the present invention is to be a kind of many curve antennas and manufacture method thereof, comprising: a radiation conductor and a bearing part; Radiation conductor outer side edges forms one of circular arc camber shape outer portion, and in one of circular arc camber fragment, one breach is set, separately central portion patterning radiation conductor conducting path inside radiation conductor; Bearing part is in order to provide radiation conductor to be covered on surface.
More than the present invention, curve antenna manufacture method is:
First step a: first sheet metal with flat surfaces is set;
Second step: sheet metal is bent to form to the radiation conductor form that outer portion has circular arc camber via gravity pressurization sizing program;
Third step: radiation conductor central portion is patterned to the conductor path of design in advance, and in the die-cut reserved linkage section of outer portion;
The 4th step: linkage section is excised.
Curve antenna and manufacture method thereof more than the present invention, production procedure through this design, except can effectively shortening radiation conductor fabrication schedule, being easy to manufacturer produces in a large number, and its product quality is easy to grasp, simultaneously without additional complexity processing operation, applicable being integrated in various radio communication product design specifications.
For making your audit crew further understand the present invention's detailed content, hereby enumerate following preferred embodiment explanation as after.
[execution mode]
Referring to the 1st figure, is the vertical view of first embodiment of the invention.Many curve antenna 1 structures comprise: a radiation conductor 11 and a bearing part 12; Radiation conductor 11 outer side edges form one of circular arc camber shape outer portion 111, and in one of circular arc camber fragment, one breach 111a are set, separately in radiation conductor 11 inner side central portion 112 patterning radiation conductor 11 conducting paths; 12 of bearing parts are in order to carry radiation conductor 11.
More than the present embodiment, curve antenna 1 approximate half-circular is bowl-shape, long limit diameter length is about 50mm, highly be about 12mm, outer portion 111 length are about 75mm, highly be about 12mm, breach 111a length is about 15mm, highly be about 5mm, central portion 112 long limit diameter lengths are about 30mm, bearing part 12 is plastic material, its size and many curve antennas 1 are approximate, radiation conductor 11 is covered on to bearing part 12 surfaces, and connect a signal pin 13, use the feed-in of antenna high-frequency signals is provided, each sectional curvature of the circular arc camber of ring portion 111 is neither identical in addition, can in response to wireless communication apparatus shell dimension, change and adjust at any time, radiation conductor 11 is closely covered on bearing part 12.
Referring to 2A to 2D and scheme, is the manufacture method steps flow chart vertical view of first embodiment of the invention.First step 21 a: first sheet metal with flat surfaces is set, and this sheet metal can be selected metallic copper material; Second step 22: sheet metal is bent to form to radiation conductor 11 forms that outer portion 111 has circular arc camber via gravity pressurization sizing program; Third step 23: the conductor path that radiation conductor 11 central portions 112 is patterned to design in advance, bearing part 12 approximate half-circular of the present embodiment are bowl-shape, therefore conductive pattern is die-cut into approximate half-circular ellipticity, and in the die-cut reserved linkage section 113 of outer portion 111; The 4th step 24: by linkage section 113 excisions, complete many curve antennas 1 through this and make.
In addition can, via galvanizing process in radiation conductor 11 plating nickel on surface, reduce radiation conductor 11 surface corrosion probability.
Refer to the 3rd figure, for first embodiment of the invention is applied to the vertical view of portable telephone.Utilize the present invention manufacture more than curve antenna 1 be assembled in after the bearing part 12 of portable telephone 3 inside, and connect a signal pin 13, utilize signal pin 13 that the feed-in of antenna high-frequency signals is provided, can carry out wireless signal transmitting-receiving and transmission,
Because each sectional curvature of ring portion 111 circular arc cambers outside the present invention's design is neither identical, can in response to portable telephone 3 plastic shell dimensions, change and adjust at any time, radiation conductor 11 is closely covered on bearing part 12.
Referring to the 4th figure, is the vertical view of second embodiment of the invention.The composition structure of the present embodiment and the first embodiment are identical, its difference is in the patterning conducting path of radiation conductor 11 inner side central portions 112 not identical, curve antenna manufacture method more than demonstration the present invention design, no matter how complicated radiation conductor 11 conducting path patterns are, neither carrying out smoothly of flow process manufactured in impact.
The present invention has met patent requirement, the actual feature with novelty, progressive and industry using value, so embodiment is not in order to limit to the present invention's scope, various changes and retouching that any those who are familiar with this art did, do not departing under the present invention's spirit and definition, all in interest field of the present invention.
