Description
[technical field]
The present invention relates to a kind of film antenna and manufacture method thereof, refer in particular to a kind of film antenna and manufacture method thereof that is used for wireless electron device.
[background technology]
Present existing antenna can be divided into built-in aerial and external antenna usually, wherein the advantage of built-in aerial is to match with electronic installation easily, and its shortcoming is to take the inner space of electronic installation, the trend of incompatibility electronic device miniaturization, and built-in aerial is because of being arranged in the electronic installation, and its gain usually can not take into account with radiation pattern.Then electronic installation is outer to have good antenna gain to external antenna because of being located at, but it generally needs to use the higher antenna material of price with the radio-frequency (RF) signal feed antenna time, and is not easy to cooperate in mechanism, is difficult for making.
Prior art related to the present invention sees also United States Patent (USP) the 6th, shown in 486, No. 837, it discloses a kind of existing film antenna structure, comprise an insulation board and plating conductive film thereon, this film antenna electrically connects by the circuit board of an a pair of contact arm and an electronic installation.Yet, should existing film antenna be by after the insulation board all surface plates thin film, again it being assembled in the electronic installation, so needing more antenna material, the assembling inconvenience, and this film antenna is assembled in the electronic installation, and its gain is good not as external antenna with radiation pattern.In addition, the position can not change again after this film antenna was assembled in the electronic installation, thereby its reception and transmission performance also can't adjust again.
[summary of the invention]
The object of the invention is to provide that a kind of reception is good, transmission performance is good and simple in structure, lower-cost film antenna.
Another purpose of the present invention is to provide a kind of manufacture method of above-mentioned film antenna.
The objective of the invention is to be achieved through the following technical solutions: film antenna of the present invention is located on the electronic installation, and wherein electronic installation comprises the connecting portion of circuit board, insulation crust and at least one flexible connection insulation crust and circuit board.Described film antenna is then by insulation crust, the connecting portion of electronic installation and be located at the outer surface of insulation crust and the conductive film on the connecting portion is constituted.
The manufacture method of film antenna of the present invention may further comprise the steps:
Ejection formation one insulation crust, described insulation crust is connected by connecting portion with the circuit board of electronic installation;
On the outer surface of insulation crust and connecting portion, plate or stick or spray layer of conductive film.
Compared with prior art, film antenna of the present invention directly is provided with layer of conductive film on the insulation crust of electronic installation, thereby has reduced the spillage of material in the antenna manufacture craft process, and cost is lower, and simple in structure, helps the assembling and the manufacturing of product.In addition, film antenna of the present invention is located on the movable shell, and it is minimum to adjust the dead angle that use angle causes its radiation pattern in use, to realize best reception and transmission performance.
